(AP) -- Anadolu Agency says Thursday authorities have detention warrants for 144 other Isis suspects.

Some 1,500 officers from the police's anti-terror and intelligence units took part in early morning raids at about 250 addresses around Ankara, the agency said.

Anadolu said some of the suspects were members of a local group that allegedly "sponsored" Isis. It didn't provide further details.

Last month, police detained dozens of Isis suspects allegedly planning an attack during a national holiday.

Turkey has suffered a series of bloody attacks blamed on Isis militants, including a New Year attack at an Istanbul nightclub that killed 39 people.
