BELGRADE, Yugoslavia (AP) --NATO warplanes knocked Serb television off the air again yesterday, and refugees fleeing Kosovo brought new reports of roaming Serb gunmen butchering villagers.

In some of the grimmest accounts so far, Kosovo refugees reaching Macedonia yesterday told relief workers of Serb paramilitaries entering villages, ordering residents out of their homes and opening fire.

"It's very alarming," said Ron Redmond, a spokesman for the U.N. High Commissioner for Refugees.

While Serbs had emptied southern towns with "clinical precision," the latest accounts depicted Serb paramilitaries combing more northerly villages and executing residents, Redmond said.

NATO leaders meeting at a summit in Washington said yesterday the allied campaign against Milosevic would succeed and pledged military protection and economic aid to Yugoslavia's neighbors for standing with the West.

"The nations of the region have risked, and even faced, armed confrontation with Serbia by facilitating and supporting our campaign to end the bloodshed in Kosovo," President Clinton said.

The Yugoslav news agency Tanjug called the three-day summit, which marked NATO's 50th anniversary, "a bloody birthday party" and labeled Clinton "the leader of the criminals."

NATO has targeted Serb TV as a key propaganda tool of Yugoslav President Slobodan Milosevic.

Serb TV resumed broadcasts in the Belgrade region several hours after the NATO strikes. But the image often was distorted and wavering because the network borrowed facilities from a private station.
