ISTANBUL: Turkish newspapers carried front-page pictures on Monday of three more men believed to be planning suicide bomb attacks for Daesh, after a suspected member of the radical group killed three Israelis and an Iranian in Istanbul.

Sunday’s attack on Istiklal Street, a long pedestrian avenue lined with international stores and foreign consulates, was the fourth suicide bombing in Turkey this year. Two in Istanbul have been blamed on Daesh, while the two others in the capital Ankara have been claimed by Kurdish militants.

At least half a dozen newspapers from across the political spectrum carried head-and-shoulders pictures of three suspected Daesh members, saying they had been given instructions to carry out further attacks in crowded areas, primarily in Istanbul.

“All provincial police units have taken action to try to capture the three terrorists suspected of being Daesh members planning sensational attacks,” the state-run Anadolu news agency said, citing unnamed security sources and describing them as part of an “active cell” in Turkey.

Interior Minister Efkan Ala on Sunday identified the Istanbul bomber as a man born in 1992 and from the southern province of Gaziantep near the Syrian border, adding that five people had been detained so far in connection with the blast.

Turkey’s Haberturk newspaper said police had been examining CCTV footage and that it appeared the suicide bomber had followed the group of Israeli tourists for several kilometers from their hotel, then waiting outside the restaurant where they ate breakfast before blowing himself up as they emerged.
