ISTANBUL — Turkey’s interior minister on Sunday identified the suicide bomber who killed himself and four foreign tourists in Istanbul as a militant with links to ISIS.
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 had no previous criminal record and five other people were detained as part of the investigation.
Saturday’s explosion killed five people, including Ozturk, and 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 linked with shops and cafes in an area that also has government offices and foreign missions.
“The identity of the terrorist who carried out this reprehensible attack has been determined…The findings obtained show that the terrorist is linked to the Daesh terror organization,” the minister said, using an alternative acronym for ISIS.
Turkey has endured six suicide bombing attacks in less than a year. The country faces a wide array of security threats including from ultra-left radicals, Kurdish rebels demanding greater autonomy who currently are locked in battle with security forces in the southeast, as well as ISIS.
Turkey is also a partner in the U.S. led coalition against ISIS and its air bases are being used to launch bombing runs against the group in neighboring Syria.
Two of the attacks this year hit the Turkish capital, Ankara. An off-shoot of the banned Kurdistan Workers’ Union claimed the Feb. 17 car bombing that killed 29 people and the March 13 suicide bombing that killed 37 people. On Jan. 12, an attack that Turkish authorities blamed on ISIS claimed the lives of a dozen German tourists visiting Istanbul’s historic sites.
Ala said Turkey was determined to press ahead with its fight against terror groups but admitted it was difficult to prevent suicide attacks.
“We are working so that they do not happen,” the minister said.
On Sunday, well-wishers placed carnations and candles at the scene of the attack, with one placard reading “We are on the streets, we are not afraid of you.”
Earlier, Israeli authorities raised the number of Israelis killed in the bombing to three, among them two who also hold American citizenship.
The third victim was identified Sunday as Avraham Goldman, 69, from Herzliya. The two others are Simha Damari, 60, from Dimona and Yonata Shor, 40, from Tel Aviv.
It was not immediately clear if the Israelis were specifically targeted. The Israelis’ bodies and other Israelis wounded in the blast were being evacuated while a senior Israeli foreign ministry official to arrive in Istanbul for meetings with Turkish officials.
