Turkish President Recep Tayyip Erdogan said Sunday a suicide bomber aged between 12 and 14 was responsible for the attack on a wedding in the Turkish city of Gaziantep that killed at least 50.

"The explosion was the result of a suicide bomber aged between 12 and 14 who either detonated (the bomb) or others detonated it," Erdogan said during a press conference from Istanbul. He repeated his assertion that initial information suggested the attack was perpetrated by the Islamic State group.
