Turkey's interior minister on Sunday identified four foreign tourists and the suicide bomber who killed himself in Istanbul as a militant with links to ISIS.
Minister Efkan Ala said the bomber was Turkish citizen Mehmet Ozturk from the southern province of Gaziantep, which borders Syria. Ozturk was born in 1992 and had no previous criminal record.
Five other people were detained as part of the investigation.
Saturday's explosion on Istiklal Street, a major shopping and tourist district in the central part of the city, killed five people, including Ozturk, and wounded dozens of others. Among the fatalities were two American-Israelis, another Israeli and an Iranian.
