Syrian rebels held onto a commanding position in a mountain range in the coastal province of Latakia, the ancestral home of Syrian President Bashar Assad, after government forces were forced to withdraw.

They said the army's attempt was the latest of several costly campaigns to seize Kubayna, after it mounted an offensive last month with Russian air power to retake main highways and trade arteries around Idlib and northern Hama now in rebel hands that have fragmented the country's war-torn economy.

The northwest represents the last big piece of territory held by rebels opposed to Assad. The coastal province of Latakia is home to the Assad family's Alawite minority.
