DAMASCUS, Syria (AP) — Foreign Minister Walid al-Moallem warned Saturday that foreign ground troops entering Syria would "return home in wooden coffins." "Any ground intervention in Syria, without the consent of the Syrian government, will be considered an aggression that should be resisted by every Syrian citizen," he told a news conference in Damascus. The offensive, aimed at encircling rebel strongholds in Aleppo, was backed by intense Russian airstrikes and sent thousands of area residents fleeing toward a closed Turkish border.
