The Lebanese prosecutor probing last summer's port explosion in Beirut filed charges on Thursday against the caretaker prime minister and three former ministers, Lebanon's official news agency said.
Judge Fadi Sawwan filed the charges against Hassan Diab and former Finance Minister Ali Hassan Khalil, as well as Ghazi Zeiter and Youssef Fenianos, both former ministers of public works.
All four were charged with negligence leading to deaths over the Aug. 4 explosion at Beirut port, which killed more than 200 people and injured thousands.
