The death toll rose to at least 15 in the collapse of an eight-story apartment building in Istanbul, Turkish officials said on Friday, but a 16-year-old boy was pulled from the rubble, still alive after almost two days buried under the debris.

The updated death toll was confirmed by Turkey’s health minister, Fahrettin Koca. The interior minister, Suleyman Soylu, told a news conference near the scene, in the Kartal district on the Asian side of the Bosporus, that another 14 people were being treated in hospitals.
