A pro-Kurdish party said yesterday that Turkish security forces have raided several of its offices and detained dozens of its members over the past few weeks. The reported raids and detentions follow some of the most violent clashes in decades between Turkish security forces and Kurdish protesters, which left 13 civilians dead. Four other people were killed in attacks in Istanbul claimed by a militant Kurdish group.The pro-Kurdish Democratic Society Party said several of its offices had been raided and some 50 party members, including five provincial leaders and nine local leaders had been detained. The party said the detentions were the result of accusations leveled by Prime Minister Recep Tayyip Erdogan against the party.
