Lebanese investigators have received the FBI’s report on the Beirut port explosion. The country will make a determination on what precisely caused the devastating blast.

Judge Fadi Sawwan, who is leading the government’s investigation into the explosion, received the FBI report on Monday. He is now awaiting reports from French and British explosive experts, the state-run National News Agency reported on Tuesday.

On Aug. 4, around 2,700 tons of ammonium nitrate exploded in a warehouse in Beirut’s port. The explosion caused more than 200 deaths and displaced hundreds of thousands of people, in addition to causing extensive damage to downtown Beirut. The ammonium nitrate exploded after catching fire, but what caused the fire is still undetermined.

Many Beirut port officials have been detained in relation to the incident and the government has said the flammable material often used in fertilizer was improperly stored. This month, Lebanon asked Interpol to arrest two people allegedly connected to the ship that brought the ammonium nitrate to Beirut in 2013.
