A Lebanese prosecutor is to question several ministers and former ministers over last week’s deadly chemical blast at Beirut port, a judicial official said Wednesday.

“The interrogations will begin with former public works minister Ghazi al-Aridi,” the official said, speaking on condition of anonymity.

“If a shortcoming or negligence on the part of one of the questioned ministers is found, the judiciary will have to state that it does not have jurisdiction to sue them,” the official explained.

The chief prosecutor will then have to transfer their file and connected evidence to parliament because the jurisdiction lies with a special council in charge of suing ministers and presidents.

The official said the current minister of public works, now working in a caretaker capacity because the government has resigned over the August 4 explosion, would also be questioned in coming days.

Several other former public works ministers, current and former ministers of finance and justice, will also be brought in, he said.

According to latest health ministry figures, the monster explosion at Beirut port killed 171, injured 6,500 and left 300,00 people temporarily homeless.

The explosion, Lebanon’s worst peacetime disaster, caused devastation across Beirut and is widely seen as a direct consequence of state incompetence and corruption.

Prime Minister Hassan Diab’s government resigned on Monday but that did little to appease protesters who want heads to roll over the disaster.

Documents seen by AFP reveal that relevant officials at every echelon of the state were aware of the danger posed by the large pile of ammonium nitrate stored for years in a port warehouse until it blew up.
