The Syrian army said Monday it was resuming military operations in a Russian-led campaign in northwest Syria that has uprooted tens of thousands and killed hundreds, blaming Turkey for not abiding by its commitments under a truce deal. Syrian state media said Thursday the ceasefire would depend on militants fulfilling a Russian-Turkish deal that tried last year to create an Idlib buffer zone. "The agreement to a truce was conditional. This did not happen. We resume our military operations against terrorist organisations," said the army statement.
