A cameraman for state-run Syrian TV was among those wounded in Saturday's clashes, according to both SANA and the Britain-based Syrian Observatory for Human Rights. The Observatory reported the deaths of four Syrian soldiers, and said a general and a paramedic were wounded. The Kurdish news agency Hawar said five government troops were killed and 26 wounded.
SANA said the clashes involved heavy machine gun fire and occurred in the village of Um Shaifa near the town of Ras al-Ayn, which was captured by Turkish-led forces last month. It later reported that government forces took the village from Turkey-backed opposition fighters.
The Free Burma Rangers, a humanitarian group active in northeast Syria, said four Syrian army soldiers were killed and seven were wounded, including a general. It said they were killed and wounded north of the town of Tal Tamr, adding that the rangers and the Kurdish Red Crescent had evacuated some of the Syrian troops.
The Observatory said the attacks involved Turkish drones.
Last week, Turkish forces captured 18 Syrian government soldiers in the area and set them free hours later following mediation by Russia.
On Saturday, Turkish Foreign Minister Mevlut Cavusoglu criticized a U.S. decision to send American troops to protect oil fields in eastern Syria, saying only Syria has rights over the country's reserves.
The U.S. has said the move is aimed at preventing the oil fields from falling into the hands of Islamic State militants. Turkey is concerned that U.S.-allied Syrian Kurdish fighters will benefit from the oil revenues. Turkey considers the Kurdish fighters as terrorists because of their links to Kurdish militants fighting inside.
"To come from tens of thousands of miles away and to say we will put the country's wealth, oil reserves to use is against international law. And we oppose it. " Cavusoglu said at the end of a regional economic cooperation meeting. "These (reserves) belong to the Syrian people and should be used in a way that benefits the people of Syria."
