Turkey is fully abiding by the agreements it reached with Russia and the United States regarding northeast Syria and is not resuming its military offensive, a security source said on Monday.

The head of Iran’s Revolutionary Guard threatened the U.S. and its allies Monday as he addressed a pro-government demonstration attended by tens of thousands of people denouncing last week’s violent protests over a fuel price hike.

Heavy fighting has continued despite a cease-fire deal in northern Syria after Turkey vowed to clear Syrian Democratic Forces from a 20-mile-deep “safe zone” between the border cities of Tal Abyad and Ras al-Ayn.
