Gunmen fired shots at U.S. peacekeepers during a military operation to detain suspected ethnic Albanian rebels entering Kosovo from Macedonia, the NATO-led peacekeeping force said Wednesday. No one was injured.

The gunfire erupted Tuesday night when someone hiding in a wooded area where the peacekeepers were on patrol shouted ``NATO, NATO, help!,'' said Maj. Randy Martin, spokesman for U.S. peacekeepers in Kosovo.

``When one of our sergeants stood up, there were several bursts of rifle fire,'' Martin said. He said the soldiers returned fire and the suspects fled the scene.
