BEIRUT: An activist group says Syrian troops are clashing with rebels near the border with Turkey.
Friday's clash appears to be the first serious violation of an internationally brokered cease-fire that went into effect a day earlier.
The Britain-based Syrian Observatory for Human Rights says the clashes are taking place on the outskirts of the northwestern village of Khirbel el-Joz that borders Turkey.
The group, which has a network of activist throughout Syria, said army deployed tanks in the area before the clash.
Regime forces halted heavy shelling and other major attacks in line with the truce that began at dawn Thursday, though there were accusations of scattered violence by both sides.
The government has ignored demands to pull troops back to barracks.
