Turkish police detained 22 local politicians from the pro-Kurdish Peoples’ Democratic Party (HDP) in Kırşehir province over alleged links to the Kurdistan Workers’ Party (PKK).

Turkish media outlets reported that late on Saturday police conducted simultaneous raids on the houses of HDP members and detained 22, including provincial chairman Demet Resuloğlu Çetin and vice chairmen Saim Özdemir and Eşref Odabaşı.

Attacks by ultranationalist groups in several Turkish cities on HDP offices have been reported in the past couple of hours.

The attacks came several hours after a car bomb attack in Kayseri province that killed 13 soldiers and injured 56 others including civilians.

The HDP condemned the Kayseri bombing and has called on the Turkish government to take immediate measures to prevent widespread attacks on the party’s offices across the country.
