The explosion killed more than 150 people and injured thousands more, Reuters previously reported. Officials have said the blast was an accident involving 2, 750 tons of ammonium nitrate that was improperly stored in a warehouse. President Donald Trump raised eyebrows earlier this week when he said hours after the attack that he had spoken with ''generals, '' who ''seem to think [the explosion] was an attack.

''But by the next day, Trump had softened on his conclusions about the explosion, telling reporters Wednesday evening, ''whatever happened, it's terrible but they don't really know what it is. ''Lebanese authorities launched an investigation into the cause of the explosion amid reports in the aftermath of the blast said that authorities had been warned about the stock of explosives since it arrived at the port in 2014.

Business Insider's Ryan Pickrell previously reported that the explosion registered as a magnitude 3. 3 earthquake, and experts say it most likely had an explosive yield of several hundred tons of TNT equivalent. Trump spoke with Lebanon's President Michel Aoun on Friday, where he expressed sympathy for the country's recovery from the attack. On a phone call with Lebanese Prime Minister Hassan Diab, US Secretary of State Mike Pompeo echoed Trump's offer of sympathy for the country, promising ''our steadfast commitment to assist the Lebanese people as they cope with the aftermath of this terrifying event. ''Lebanese officials unloaded a 'floating bomb' and apparently ignored warnings for years, according to reports.
