Earlier this week Turkish and US backed FSA units launched an offensive along the Syrian-Turkish border and managed to capture dozen or so villages and a larger ISIS controlled stronghold. Puts then in a nice position to attempt a pincer and entrap the last ISIS strongholds in North aleppo. However, pushing so far east left their center open and launched a small counter attack last night and managed to recapture some small villages, believe this is from that or the morning after when FSA regrouped and counter attacked.
