russia is widening the geographic scope of the fighting and concern it could be laying the groundwork to possibly use chemical weapons. since we left you last night russia targeted two cities here in western ukraine. air ride sirens were sounding as we went off the air, though the actual strikes were about 90 minutes from here in either direction. now, this is video which is just 70 miles or so from the nato ally border poland. according to the regional governor the local airport was hit by four bomber fire missiles, killing two people. a military airfield about 150 miles south was also hit. now, north of kyiv those artillery units we showed you last night which had redeployed from the big convoy have now apparently gone into action.
