Beirut, Aug 7 (IANS): Sixteen employees at the Port of Beirut have been arrested over the two deadly explosions in the Lebanese capital that claimed the lives of over 135 people and left thousands others injured, a top official announced.

On Thursday evening, Government Commissioner to the Military Tribunal Judge Fadi Akiki said that more than 18 people have been questioned so far, including port and customs officials as well as people in charge of maintenance at the hangar where explosive materials have been stored for years, Xinhua news agency reported.

Two huge explosions rocked the Port of Beirut on Tuesday evening, killing at least 137 people and injuring nearly 5,000 others, while causing massive damages in the city.

Primary information has revealed that ammonium nitrate stored since 2014 in the port's warehouse No. 12 might have caused the explosions.
