Istanbul, Turkey (CNN) -- Turkey's use of F-16 warplanes to force a Syrian airliner to land and be searched on Wednesday demonstrated a blunt warning to Damascus a week after five Turkish civilians were killed by cross-border artillery fire from Syria. On Thursday, a day after the Syrian passenger plane was forced to land at Ankara's airport, Turkey's Prime Minister Recep Tayyip Erdogan announced at a news conference that cargo confiscated from the aircraft included "items ... traveling from Russia's agency that exports weapons munitions and military supplies to Syria's defense ministry." Turkish officials said the use of F-16's to intercept the plane as it flew from Moscow to Damascus was a show of force, to illustrate Turkey would not tolerate the use of its airspace for weapons shipments to Syria.
