More than 70 US armoured vehicles escorted by helicopters drove past the northern Syrian town of Tal Tamr carrying military equipment on Sunday October 20th, an AFP reporter said.
A US-brokered ceasefire was made effective as of late Thursday, giving Kurdish forces a deadline of Tuesday evening to withdraw from a "safe zone", an area Ankara said it wanted to create along its southern border.
A US-brokered ceasefire was announced late Thursday after violence killed scores from both sides and displaced hundreds of thousands from their homes, the Egyptian Al-Ahram daily has reported.
Some of the forces flew the American flag as the convoy made its way eastwards along a highway crossing the town, he said.
The Syrian Observatory for the Human Rights, war monitor, said the convoy was evacuating the Sarrin military base.
The convoy was heading to the town of Hassakeh, further east, said the Britain-based monitor, which relies on sources inside Syria for its information.
According to Observatory chief Rami Abdel Rahman, Sarrin is situated more than 30 kilometres (19 miles) south of the border town of Kobane, on the edges of the Turkish-desired "safe zone."
