US air strikes target Libyan terror camps

US AIR force bombers have attacked Islamic State military camps in Libya.

The attack by the B-2 planes was aimed at eliminating extremists who had escaped the former IS stronghold of Sirte, a defence official said.

The spokesman said the camps were located about 28 miles south west of the central coastal city of Sirte.

The strikes were carried out overnight and were authorised by President Barack Obama, marking perhaps the final use of military force by a wartime president who intervened in Libya in 2011 as part of a coalition that ultimately toppled dictator Muammar Gaddafi.

The defence official said the latest strikes were aimed at hitting IS militants who had escaped from Sirte following US strikes.
