KFOR peacekeepers in Kosovo are trying to stop ethnic Albanian acts of revenge against Serbs. A discussion with three experts follows this report by Independent Television News.

MARGARET WARNER: We lead tonight with a look at how peace is working -- and not working -- in Kosovo, especially for Serbs and Albanians living in the same communities. We start with a report by Lindsey Hilsum of Independent Television News from the town of Vitina.

LINDSEY HILSUM: Supplies for the poorest and most frightened: Elderly Serbs who dare not leave their house for fear of attack now dependent on Jane Muigai from the U.N. High Commission for Refugees. They take her to see the neighbor's house shot at just two days ago.

JANE MUIGAI: But did the bullet go into the house? Can I see?

LINDSEY HILSUM: They ask Jane if they can leave with her now. She tries to suggest they move to a nearby Serb enclave.

JANE MUIGAI: Would you like to...

LINDSEY HILSUM: But they say they don't want to stay in Kosovo any longer. Some of these Serbs were originally from Croatia. They're about to become refugees for the second time around. Watching his fellow Serbs attack Albanians during the war, Kantar Janko felt a sense of deja vu.

KANTAR JANKO: (speaking through interpreter) I was thinking it would come back at them, because I saw the same thing in Croatia. Here, volunteers from Serbia burned the Albanian houses. When the Serbs retreated, Albanians burned their houses.

LINDSEY HILSUM: We left the house, but Albanians in Vitina had noticed our interest in the Serbs.

MAN: You want to know truth what happened here, come to see my house.

LINDSEY HILSUM: You tell me what happened. Tell me what happened here.

MAN: My house burned.

LINDSEY HILSUM: Then the Albanian turned and accused one of the Serbs in the group.

MAN: (speaking through interpreter) You were in uniform and you carried a gun like this. You were on the street there. All of Vitina could be a witness. I will be the first witness. You wait for justice.

MAN RESPONDING TO CHARGE: (speaking through interpreter) I would not still be here if I had done that.

LINDSEY HILSUM: A few miles away, in Lubjan, a detention center run by the British military. Many of the Serbs here have been accused of murder or house burning. But there are Albanians here, too, accused of similar serious crimes. But in the end, who's going to judge? Crime's the biggest problem Kosovo is facing now. Here, the British are extending a detention facility, and they are organizing temporary courts with local judges. Within an atmosphere of such mistrust, opportunism and revenge are taking the place of justice. Albanians burned the Serbian parts of Vitina two weeks ago. The Serbs say the Albanian leadership wants to force them all out of Kosovo. Whether that's true or not, Albanian looters seem to feel no sense of guilt. We went back to Vitina as the Serbs were preparing to leave.

JANE MUGAI: Is everybody ready? Even the old ladies?

LINDSEY HILSUM: UNHCR will take them to the last checkpoint, and they'll find their own way to towns in Serbia. The Serbs of Vitina don't trust KFOR, the foreign troops sent to protect them from the wrath of the Albanians. Many would say they've got what they deserve. How many Serbs stood up and said no when Albanians were being forced out? But few here, Albanians or Serbs, believe NATO leaders' words about the multiethnic Kosovo.
