KAHRAMANMARAS, Turkey (AP) — A teenager was pulled largely unscathed from beneath the rubble of a collapsed building in the Turkish city of Gaziantep early Friday, in a dramatic rescue that belied the reality four days after a catastrophic earthquake that killed more than 20,000, that the possibility of finding many more survivors was increasingly unlikely. The 7.8 magnitude earthquake hit the border region between Turkey and Syria, an area home to more than 13.5 million people. Bodies lay wrapped in blankets, rugs and tarps in the streets of some cities, with morgues and cemeteries overwhelmed.
