ISTANBUL: Turkish police detained 15 people in raids early on Friday targeting the Islamic State militant group in the western coastal province of Izmir, the private Dogan news agency reported.
Among those detained were people who fought for Islamic State in neighboring Syria and who trained others to fight for the group, it said.

Among those they had trained was a man now being sought by police in connection with bomb attacks on offices of a pro-Kurdish party in southern Turkey last year and who was regarded as a potential suicide bomber, Dogan said.
Turkish authorities say a Turkish member of Islamic State was responsible for a suicide bombing in central Istanbul on March 19 that killed three Israelis and an Iranian. That was the fourth suicide bombing in Turkey this year and the second to be blamed on Islamic State.
