IZYUM, Ukraine (AP) — An Associated Press reporter has heard heavy gunfire at an airport in eastern Ukraine after the government sent in army troops to retake control from pro-Russian militiamen.

The mayor of Kramatorsk said Ukrainian troops have now occupied the military airport and are blocking its entrance.
