A Turkish news agency and Syrian activists say Turkey-backed forces have reached the center of the Syrian town of Afrin, the target of a nearly two-month-old Turkish offensive against a Syrian Kurdish militia.

Turkey views the Kurdish forces in the Afrin enclave along the border as terrorists because of their links to the Kurdish insurgency inside Turkey.

Turkey's private Dogan news agency on Sunday reported that the Turkish-backed Syrian fighters "established control" in the town center. Footage showed armed men walking among derelict buildings amid sporadic gunfire.

The Syrian Observatory for Human Rights says the Syrian fighters entered the town with Turkish forces amid intensive airstrikes. Thousands of residents have fled in recent days.
