Islamist militia resumed their assault on Libya’s main international airport in Tripoli, on Sunday, killing at least two people, a Libyan security official said according to the Associated Press.

The victims were killed after a stray rocket hit their house as rival militias exchanged heavy fire around Tripoli's international airport, the official said on condition.

The bombardment resumed early Sunday two days after an abortive truce with the rival former rebels that control it.

“The airport was attacked this morning with mortar rounds, rockets and tank fire,” Al-Jilani al-Dahesh, an airport security official said, according to Agence France-Presse.

“It was the most intense bombardment so far,” he added.

Islamist militia first attacked the airport last Sunday, forcing a halt to all flights.

Their continued offensive has caused extensive damage to planes and airport infrastructure that aviation officials say will keep it closed for months.
