Turkey's defense chief said Sunday that his country's troops won't evacuate their 12 observation posts in rebel-held northwestern Syria.
That's even as a Syrian government offensive pushed deeper into Idlib province, the last remaining opposition stronghold.
Turkey -- a strong backer of some of the rebels fighting Syrian President Bashar Assad's forces -- has a dozen observation posts in Idlib province, as part of an agreement reached last year with Russia, a main supporter of Assad.
