Minister Efkan Ala said the bomber was Turkish citizen Mehmet Ozturk, who was born in 1992 in Gaziantep province, which borders Syria. He said Ozturk wasn't on any list of wanted suspects and five other people were detained as part of the investigation.
Saturday's explosion wounded dozens of others. Among the fatalities were two American-Israelis, another Israeli and an Iranian. The attack targeted Istanbul's pedestrian Istiklal Street, which is lined with shops and cafes in an area that also has government offices and foreign missions.
