Turkish Prime Minister Binali Yildirim said Monday that it's unclear at the present time whether the attacker was "a child or an adult." President Recep Tayyip Erdogan said on Sunday that the bomber was between 12 and 14 years old. The bombing at a wedding Saturday night killed 54 people in Gaziantep near the Syrian border. Twenty-two of the 54 killed were under 14, a Turkish official said.
