International aid agencies are stepping up efforts to help millions of homeless people, many sleeping in tents, mosques, schools or cars, 11 days after a massive earthquake hit Turkey and Syria killing more than 43,000.

Two people were reported to have been pulled alive from the rubble in Turkey on Thursday, but such rescues have become increasingly rare, leaving anger to smoulder as hope fades.

A 17-year-old girl was extracted from the ruins of a collapsed apartment bloc in Turkey's southeastern Kahramanmaras province, broadcaster TRT Haber reported, 248 hours since the 7.8 magnitude earthquake struck in the dead of night on Feb. 6.
