US warplanes launch bombing campaign on Islamic State in Libya
US planes bombed Islamic State targets in Libya on August 1, responding to the UN-backed government's request to help push the militants from their former stronghold of Sirte in what US officials described as the start of a sustained campaign against the extremist group in the city.
"The first air strikes were carried out at specific locations in Sirte today causing severe losses to enemy ranks," Prime Minster Fayez Seraj said on state TV. Pentagon spokesman Peter Cook said the strikes did not have "an end point at this particular moment in time".
Forces allied with Seraj have been battling Islamic State in Sirte - the home town of former dictator Muammar Gaddafi - since May.
The militants seized the Mediterranean coastal city last year, making it their most important base outside Syria and Iraq. But they are now besieged in a few square kilometers of the center, where they hold strategic sites, including the Ouagadougou conference hall, the central hospital and the university.
Seraj said the Presidential Council of his Government of National Accord, or GNA, had decided to "activate" its participation in the international coalition against Islamic State and "request the United States to carry out targeted air strikes on Daesh (Islamic State)."
The air strikes on August 1 - which were authorized by US President Barack Obama - hit an Islamic State tank and two vehicles that posed a threat to forces aligned with Libya's GNA, Cook said.
