BAGHDAD — Iraq’s Kurdish regional government called on the Kurdistan Worker’s Party to withdraw from Iraq’s Kurdish territory Saturday to prevent civilian deaths amid a campaign of Turkish air strikes targeting the group. A statement from the office of Kurdish President Massoud Barzani said the Kurdistan Workers’ Party, known as the PKK, “should withdraw its fighters from the Kurdish region so to ensure the civilians of Kurdistan don’t become victims of that fighting and conflict.” The statement also condemned Turkey for bombing civilians, following reports that civilian homes were damaged in air strikes in northwestern Iraq.
