ANKARA - Turkish police used pepper gas to disperse pro-Kurdish protesters in Ankara and Istanbul on Sunday, detaining at least 12 people in Istanbul, Reuters witnesses said.
The protesters were demonstrating against the Turkish military's operation against a U.S.-backed Kurdish militia in Syria's northern Afrin province.
Turkish President Tayyip Erdogan had earlier warned supporters of the pro-Kurdish opposition not to protest the military's operation, saying security forces would intervene if they demonstrated.
