Interior Minister Ali Yerlikaya said eight police and another security force member were wounded in a raid on a property in the town of Yalova, on the Sea of Marmara coast south of Istanbul.

More than 100 addresses were raided nationwide early on Monday.

Türkiye has stepped up operations against suspected Daesh militants this year, as the group returns to prominence globally.

The US carried out a strike against the militants in northwest Nigeria last week, while two gunmen who attacked a Hanukkah event at Sydney’s Bondi Beach this month appeared to be inspired by Daesh actions, Australian police have said.

On December 19, the US military launched large-scale strikes against dozens of Daesh targets in Syria in retaliation for an attack on American personnel.

Police raided the house in Yalova on the suspicion that militants were hiding there overnight.

Sporadic gunfire was heard during the operation, which lasted nearly eight hours, according to a Reuters photographer at the scene.

Last week, Turkish police detained 115 suspected Daesh members, who they said were planning to carry out attacks on Christmas and New Year celebrations in the country.

Yerlikaya told reporters that the militants killed in Monday’s attack were all Turkish citizens, adding that five women and six children were brought out of the property alive.

In the last month, police arrested a total of 138 Daesh suspects and carried out simultaneous operations on Monday morning at 108 different addresses in 15 provinces, he added.

In a post on X, President Tayyip Erdogan offered his condolences to the families of the police officers killed, and said Türkiye’s fight with “the bloody-handed villains who threaten the peace of our people and security of our state” will continue “both within our borders and beyond them.”
