Imad Keshli, an employee and truck driver at the port of Beirut, revealed that on August 4, last year he realized strange behaviors and movements at the port.

Keshli said during a television interview on Wednesday, “I was a truck driver and transported twice a quantity of nitrates to South Lebanon.”

He added: “It took me a year to have the courage to talk, as I never complained my concerns. There is no one whom I can trust to talk to him about what I have seen.”
