Istanbul: Turkish police detained six people including local officials from the pro-Kurdish People's Democratic Party (HDP) on Friday in a raid on one of its Istanbul offices, days after President Tayyip Erdogan said he backed legal action against its members.
Riot police and special forces took part in the operation, according to the state-run Anadolu Agency, which said the action was part of a crackdown on urban networks of the Kurdistan Workers Party (PKK) militant group's youth wing.
Erdogan and the government accuse the HDP, parliament's third-biggest party, of being an extension of the PKK, which has fought a three-decade insurgency for greater Kurdish autonomy in the southeast and which is considered a terrorist group by Turkey, the United States and the European Union.
HDP says it is opposed to violence and wants a peaceful solution for Turkey's Kurds.
The detentions come less than 48 hours after Erdogan said some HDP lawmakers and local mayors were behaving like members of a terrorist organisation and that their positions should not shield them from prosecution.
Istanbul police said in a statement that the operation was part of an investigation into a June 2015 murder suspected to have been carried out by PKK members and was based on a tip-off that the murder weapon was in the HDP building.
The predominantly Kurdish southeast has sunk into violence after a two-year ceasefire between the PKK and the state collapsed last July, reviving a conflict that has crippled the region for three decades, killing more than 40,000 people.
On Friday, six Turkish soldiers were wounded in clashes in Sur, the historic district of southeastern Diyarbakir province that has been under a police curfew for over a month, security sources said. In Silopi, bordering Iraq, 58 PKK militants were captured while trying to flee, the Turkish military said.
The shift in fighting from the countryside to urban centres has left civilians caught in the middle. According to HDP figures, 72 civilians in three southeastern towns have been killed since December 14, when the latest military campaign began.
Thousands of people have left their homes in Sur. Residents complain indiscriminate operations and round-the-clock curfews have left even the sick unable to get to hospital.
Erdogan has said 3,100 PKK members were killed in operations inside and outside the country in 2015.
