Incident

How the Beirut port explosion investigation unfolded

On 4 August 2020 about 2,750 tonnes of ammonium nitrate stored at the Port of Beirut since 2014 exploded, killing 218 people according to Human Rights Watch. The judicial investigation was stalled for years by legal challenges from officials it sought to charge. Judge Tarek Bitar concluded it in March 2026 and received the prosecution's review in September, but no indictment had been reported as of 1 November 2026.
