Turkey's army and rebel allies battled U.S.-backed Kurdish militia in Syria's Afrin province on Sunday, stepping up a two-day-old campaign against YPG fighters that has opened a new front in Syria's civil war.
Amid U.S. calls for restraint, Turkish artillery pounded YPG positions, while rockets fired from inside Syria slammed into two Turkish border towns, wounding dozens, according to the local governor's office and a witness.
Turkey began its push to clear YPG fighters from a northwestern enclave of Syria on Saturday when it launched artillery and air strikes against their positions in Afrin in what it called "Operation Olive Branch".
Turkey considers the YPG a terrorist organisation and has been infuriated by U.S. support for the fighters. Washington, which is backing the YPG in the battle against Islamic State in Syria, on Sunday said it was concerned about the situation.
"Our jets took off and started bombing. And now the ground operation is underway. Now we see how the YPG ... are fleeing in Afrin," President Tayyip Erdogan said. "We will chase them. God willing, we will complete this operation very quickly."
Intense Turkish artillery fire and air strikes continued to hit some villages, the YPG said, while fierce battles raged to the north and west of Afrin against Turkish forces and their rebel allies, said Birusk Hasaka, a YPG spokesman in Afrin.
Turkey, which is backing the Free Syrian Army rebel factions in northern Syria, wants to create a 30-km (19 mile) "safe zone" in the region, broadcaster HaberTurk quoted the prime minister, Binali Yildirim, as saying.
But it is targeting the U.S.-supported YPG at a time Turkey's ties with NATO ally Washington are deeply strained.
"We urge Turkey to exercise restraint and ensure that its military operations remain limited in scope and duration and scrupulous to avoid civilian casualties," U.S. State Department Spokeswoman Heather Nauert said.
Turkey did advise the United States before taking action, the U.S. Defense Secretary, Jim Mattis, said on Sunday, adding "We'll work this out".
Turkey said it had hit targets including hideouts used by Kurdish militants. Erdogan said some of Turkey's allies had provided the YPG with 2,000 plane shipments and 5,000 truckloads of ammunition, comments that appeared to be aimed at the United States.
