Idlib province: Syrian forces on Sunday pushed deeper in their offensive on the last remaining rebel stronghold in the country's northwest, getting close to a Turkish observation post in the area, opposition activists said.
The Britain-based Syrian Observatory for Human Rights and the opposition's Syrian Civil Defence reported the shelling and airstrikes on rebel-held villages in Idlib, saying that at least one civilian was killed.
The province of Idlib has been at the centre of a Syrian forces' push under the cover of airstrikes in recent weeks, with more than a dozen villages captured.
The offensive has already forced tens of thousands of civilians to abandon their homes and flee, including thousands who crossed into neighbouring Turkey seeking safety.
The attacks resumed after a cease-fire in force since the end of August collapsed recently.
Turkey has backed Syrian rebels in the neighbouring country's civil war, now in its ninth year.
Saraqeb and Maaret al-Numan are two major rebel-held towns on the highway linking the capital Damascus with the northern city of Aleppo, Syria's largest.
The two towns have been emptied of civilians since becoming the target of the offensive, which aims to reopen the highway closed since 2012.
