Beirut Port Ammonium Nitrate Explosion Cover-Up (4 August 2020)

Introduction

At 6:08 p.m. on 4 August 2020, an explosion at the Port of Beirut killed 218 people, injured more than 7,000, displaced approximately 300,000, and caused damage estimated at $15 billion. The blast — one of the largest non-nuclear explosions in history — originated in Hangar 12, where approximately 2,750 tonnes of ammonium nitrate had been stored since 2014. The material had been impounded from the cargo ship MV Rhosus, which had docked in Beirut in 2013 and been declared unseaworthy.

What makes the Beirut explosion a confirmed cover-up rather than merely a catastrophic accident is the documented paper trail of warnings that were received and ignored, and the systematic obstruction of subsequent judicial investigations by political figures with apparent interests in preventing accountability.

The Six Years of Storage: MV Rhosus

The MV Rhosus, sailing under a Moldovan flag, arrived in Beirut in November 2013 carrying 2,750 tonnes of ammonium nitrate originally destined for Mozambique. The ship's owner, Igor Grechushkin, abandoned both vessel and cargo after the ship was impounded over unpaid port fees. Lebanese authorities, unable to find a buyer or arrange removal, stored the ammonium nitrate in Hangar 12 of the port — a warehouse not designed or equipped for such storage.

The storage of 2,750 tonnes of a highly explosive industrial material in an unsealed warehouse adjacent to a densely populated city was not a secret. It was documented in customs records, port authority files, and government correspondence.

Documented Warnings

The warnings were not informal or ambiguous:

Badri Daher's six letters: Badri Daher, director-general of Lebanese Customs, sent letters in 2014, 2015, 2016, 2017 (multiple), and 2018 to the judiciary requesting authorisation to re-export or destroy the ammonium nitrate. Each letter went unanswered or was referred to another authority without resolution.

State Security report, 20 July 2020: Lebanese State Security sent a formal written report to President Michel Aoun and Prime Minister Hassan Diab on 20 July 2020 — just 15 days before the explosion — explicitly stating that 2,750 tonnes of ammonium nitrate stored in the port posed an imminent danger and recommending immediate action. The report was received and acknowledged. No action was taken.

Military intelligence warnings: Separate reporting indicates that military intelligence had also flagged the storage situation in the period before the explosion.

Judicial Obstruction

Two successive judicial investigations were launched:

Military judge Fadi Sawan began investigating the explosion in 2020 and charged several current and former ministers with negligence and criminal responsibility. Senior political figures — including former Prime Ministers Hassan Diab and Saad Hariri — invoked parliamentary immunity provisions to block questioning. Sawan was removed from the case in February 2021 following a successful legal challenge by two of the ministers he had charged.

Civilian judge Tarek Bitar was appointed to continue the investigation and issued summonses to a wider circle of officials, including current minister Ali Hassan Khalil and former minister Ghazi Zeaiter, both affiliated with the Amal Movement led by Parliament Speaker Nabih Berri. Hezbollah and Amal-linked politicians publicly demanded Bitar's removal, and Hezbollah Secretary-General Hassan Nasrallah called him biased. Bitar's investigation was suspended multiple times by legal challenges and court orders obtained by politically connected defendants. As of 2025 the investigation remains effectively paralysed.

Accountability Gap

No senior Lebanese official, minister, or political figure has been convicted of criminal responsibility for the explosion as of 2026. The families of victims have pursued accountability through Lebanese courts, international human rights bodies, and public campaigning without success. France, the United States, and other foreign governments have expressed concern about the obstruction of the investigation.

Verdict

Confirmed. The explosion was not unforeseeable: 2,750 tonnes of ammonium nitrate stored for six years in a port warehouse, with documented written warnings reaching the highest levels of government 15 days before the detonation. The subsequent obstruction of two separate judicial investigations by politically connected figures constitutes a documented cover-up of accountability rather than a cover-up of the explosion's cause. The cause is known; the accountability has been deliberately prevented.

What Would Change Our Assessment

• Criminal conviction of officials responsible for ignoring the documented warnings
• Full transparency on which officials received State Security's 20 July 2020 report and what instructions, if any, were issued
• Unobstructed completion of the Bitar judicial inquiry

The FBI's Contested Tonnage Estimate

A detail often missing from summaries of the Beirut blast is that the U.S. Federal Bureau of Investigation, which assisted Lebanese authorities with technical analysis, concluded in an October 7, 2020 report that only approximately 552 metric tonnes of ammonium nitrate actually detonated in Hangar 12 — roughly one-fifth of the 2,754 tonnes originally unloaded from the MV Rhosus in 2013. The FBI's language was blunt about the size of the gap: investigators found "it is not logical" that the full original shipment was present at the moment of detonation. A senior Lebanese official who reviewed the findings agreed with the FBI's tonnage calculation but said there were "no firm conclusions" as to why roughly four-fifths of the material was unaccounted for. Two competing explanations have circulated since: that a substantial portion of the ammonium nitrate was stolen or diverted from the warehouse at some point during the six years of storage, or that only part of the stockpile detonated while the rest was destroyed, dispersed, or blown into the harbor by the blast itself. Neither theory has been confirmed. This is a genuine open question in the case, not a challenge to the underlying negligence finding — even a fifth of the original shipment produced one of the largest non-nuclear explosions on record, and the unresolved discrepancy is itself one more example of the accounting failures that plagued the port's handling of the cargo from the start.

Documented Warnings Predate the Final Years

Human Rights Watch's August 2021 report, "They Killed Us From the Inside," traced the paper trail of warnings back further than the widely cited 2014–2018 customs letters. HRW documented that a customs official first flagged the dangerous nature of the Rhosus cargo on February 21, 2014 — within months of the ship's arrival. On April 7, 2014, the Baroudi and Associates law firm warned the Ministry of Public Works and Transport in writing that the ammonium nitrate was "extremely hazardous" and noted explicitly that it is "used in the manufacture of explosives." On May 16, 2014, the Director General of General Security informed then-Minister Ghazi Zeaiter that "several tonnes of a very dangerous substance" were sitting in the port. HRW's report also states that on August 3, 2020 — the day before the explosion — then-Minister of Public Works Michel Najjar personally received the State Security report warning of the risk. HRW concluded that the pattern of specific, repeated, written warnings reaching named officials by name and title, over a period of more than six years, supports its assessment that several officials were not merely negligent but, in the organization's words, may have "foresaw the death that the ammonium nitrate's presence in the port could result in" and tacitly accepted that risk — a standard that could meet the threshold for homicide with probable intent under Lebanese law, not just administrative negligence.

What Actually Ignited the Fire — Still Unresolved

The detonation of the ammonium nitrate is not in dispute, but what started the fire in Hangar 12 that triggered it has never been established to a legal standard. The leading account, consistent with reporting from L'Orient Today and other outlets, holds that port workers or welding contractors carrying out repairs to the hangar's door produced sparks that ignited flammable materials stored alongside the ammonium nitrate — including a cache of fireworks, tires, and other combustibles that should never have shared a warehouse with an explosive oxidizer in the first place. But investigators, including a French judicial team that assisted Lebanon and the FBI itself, have both said they could not conclusively determine whether the fire began through negligence (a welding accident, an electrical fault, or a discarded cigarette) or through some other, undetermined cause. No investigation has produced forensic proof of the ignition source. This gap does not affect the confirmed verdict on the cover-up — the negligent, six-year storage of the material is separately and independently documented — but it means one specific factual question, the spark itself, remains formally open.

External-Attack Theories: Examined and Unsupported

In the explosion's immediate aftermath, viral videos claimed to show a missile or airstrike striking the warehouse moments before detonation. Investigative outlet Bellingcat conducted frame-by-frame video analysis, geolocation using landmarks including the Mohammad Al-Amin Mosque's minarets, and synchronization of multiple independent camera angles. It found no footage showing any projectile impact; the objects presented as missiles were either birds (whose flapping motion is visible when the clips are slowed down) or crude CGI overlays added to genuine footage, in one case visible for only two frames before vanishing. Separately, nuclear-weapons experts dismissed claims of a nuclear detonation because the blast lacked the blinding flash and thermal pulse that characterize a nuclear explosion. Claims that the "jet sounds" heard on video indicated an aircraft were traced instead to the acoustic signature of the warehouse fire's own small explosions and rushes of air intake. None of this evidence has been contradicted by later reporting. At the same time, official language has stopped short of ruling out an external strike with total certainty: judge Tarek Bitar was reported by journalists in mid-2026 to have said he was "80 percent certain" the blast was not caused by an Israeli missile — a notable hedge from the investigator with the most complete access to the evidence, even though no physical evidence for a strike has ever surfaced in five years of inquiry. Separately, Human Rights Watch's report noted, without endorsing, that an intentional act by Hezbollah has also been raised as a theoretical explanation; no investigation has produced supporting evidence for that theory either.

The Stalled-Then-Resumed Bitar Investigation (2023–2026)

Judge Tarek Bitar's domestic investigation was effectively frozen for roughly two years after Lebanon's then-prosecutor general, Ghassan Oueidat, moved in January 2023 to release detained suspects, order security forces not to execute Bitar's summonses, and file a legal complaint against Bitar himself for "usurping power." The freeze held until Oueidat's retirement and the appointment of PM Nawaf Salam's government in early 2025, alongside a shift in Lebanon's domestic balance of power following the 2023–2024 Israel–Hezbollah war that weakened Hezbollah's political leverage. Bitar quietly resumed his work within days of the new government's formation. His successor as prosecutor general, Jamal Hajjar, reversed Oueidat's freezing orders in March 2025, after which several previously uncooperative officials — including former prime minister Hassan Diab and Major Generals Abbas Ibrahim and Tony Saliba — appeared for questioning. On January 16, 2025, a Lebanese court found former ministers Ali Hassan Khalil and Ghazi Zeaiter guilty of "abuse of right" specifically for their yearslong campaign of legal challenges aimed at obstructing Bitar — a rare judicial acknowledgment that the obstruction itself, not just the original storage negligence, had a name and a verdict. On March 30, 2026, Bitar formally concluded his investigation and referred the full case file — covering roughly 70 defendants, including politicians, security officials, and civil servants — to Prosecutor General Hajjar for review before formal indictments can be issued. As of that referral, no one remained in detention and no indictments had yet been handed down.

The Ship Owner Resurfaces: Grechushkin's Arrest and Extradition Fight

For nearly five years, Igor Grechushkin — the Russian-Cypriot businessman who owned the MV Rhosus and abandoned both ship and cargo in Beirut — remained beyond Lebanese reach despite an outstanding arrest warrant. That changed on September 16, 2025, when Bulgarian police arrested him at Sofia's airport as he arrived from Cyprus, acting on an Interpol notice tied to the original Lebanese warrant. Lebanon's justice minister said at the time that "a state that is not able to give answers and ensure accountability to its citizens is a state not fulfilling its role." Lebanese authorities moved to seek his extradition, but on December 10, 2025, the Sofia City Court rejected the request, ruling that Lebanon had not provided sufficient assurance that Grechushkin would be shielded from a possible death sentence — Lebanon retains capital punishment on its books, which several European states cite as a bar to extradition. The ruling was appealable, and Grechushkin remained in Bulgarian custody pending further proceedings. His arrest marked the first time in the case's history that a central figure in the cargo's original arrival faced any form of detention.

International Pressure: UN Experts and Amnesty International

Outside Lebanon's courts, international bodies have repeatedly pressed for accountability. On August 3, 2022, a group of 37 independent UN human rights experts appointed by the Human Rights Council issued a joint statement on the blast's second anniversary, saying that "this tragedy marked one of the largest non-nuclear blasts in recent memory, yet the world has done nothing to find out why it happened," and called for an international investigation "to be initiated without delay." Amnesty International echoed the same call on the fifth anniversary in August 2025, describing a death toll of more than 236 (a figure that reflects fatalities recorded to that point, including some who later died of their injuries) and quoting Amnesty Lebanon campaigner Reina Wehbi: "Justice delayed is justice denied. The families... have waited an intolerable five years." Amnesty's demands were specific: a comprehensive, unobstructed investigation establishing the full chain of responsibility, removal of the procedural barriers used to stall Bitar's work, guarantees of judicial independence, and reform of the civil and criminal procedure codes that obstructionist officials repeatedly exploited to freeze the case. Neither the Human Rights Council nor any single state has yet mandated the independent international mechanism the UN experts requested.

Where Legal Accountability Stands Today

Taken together, the FBI's unresolved tonnage question, the still-undetermined ignition source, the debunked-but-not-100%-excluded external-attack theories, and the file now sitting with Lebanon's prosecutor general all point to the same conclusion already reflected in this profile's verdict: the physical cause of the disaster — six years of unsafe ammonium nitrate storage, ignored by officials who were warned repeatedly and in writing — is established beyond reasonable dispute. What remains genuinely unresolved, more than six years on, is whether any individual will ever be criminally convicted for it. As of the March 2026 referral to the prosecutor general, that adjudication has not happened.
