U.S. launches airstrike campaign against Islamic State in Libya

U.S. attack jets and drones launched airstrikes inside Libya on Monday against multiple Islamic State targets, marking a further expansion of President Obama's war against the militant group.

The warplanes targeted Islamic State transport vehicles and tanks that had been menacing Libyan forces inside the densely populated city of Surt, along the central Mediterranean coast where the Sunni extremist group has built a stronghold.

The strikes, the start of an ongoing campaign, will give the U.S. military a more prominent role in war-torn Libya and open a new front less than six months before Obama leaves office.
