Turkish police carried out raids against suspected Daesh cells in Istanbul and the Aegean coastal city of Izmir, two days after a triple suicide bombing killed 42 people at Istanbul airport.
Police stormed a number of locations on the European and Asian sides of Istanbul in search of Daesh terrorists, reports said.
Special operations forces were actively involved in the operation, which came two days after a terror attack on Istanbul airport, for which officials blame Daesh terror network.
Police enforced entry locations, believed to house Daesh terrorists, during raids carried out across the districts of Pendik, Başakşehir and Sultanbeyli.
There is no report of how many have been detained by police.
Nine suspected militants, thought to have been in contact with Daesh members in Syria, were meanwhile detained in raids in three districts in Izmir.
