Refugees 'trapped in wasteland'
Belongings lay strewn around the abandoned camp at Blace

The two main border points between Kosovo and Albania have been closed. And Serbian police have apparently told queues of people, who had been waiting without food on the Kosovo side of the border crossing at Blace in Macedonia, to go home.
BBC Correspondent Paul Wood says refugees in Macedonia have dismissed this as a cynical ploy by Yugoslav President Slobodan Milosevic to demonstrate some kind of normality in Kosovo.
But diplomats at the Luxembourg meeting say serious differences are emerging over potential solutions.
France is said to be strongly opposed to a formal airlift, saying it would contribute to ethnic cleansing in Kosovo. Other countries, including Britain and Italy, object to plans for each EU country to be allocated a quota of refugees.
Our correspondent says it has always been Yugoslavia's official position that Kosovo Albanians had full rights to remain in their homes. Now the authorities seem to be acting to show they mean what they say.
"We would like to know what is happening to these people."
Nato spokesman Jamie Shea said the alliance was alarmed by the border closures.
"It is quite another to push them back into a wasteland where there is no food, very little water, very little medical supplies and where everything has been looted."
He also said Nato suspected there are three mass graves in Kosovo, and estimated that 50 villages in the province had been torched in the past four days.
Mr Shea said Nato had put five demands to President Slobodan Milosevic and if he agreed to all of them the alliance would stop its air operations.
Signs of genocide
UN Secretary-General Kofi Annan said he saw signs that Serbian authorities were committing genocide in Kosovo.
Mr Rubin said he was naming the officers "as a warning that the world is watching".
And US Defence Secretary William Cohen has said Nato will intensify attacks on Serb army units in Kosovo in the coming days.
'Missing' refugees in Albania
Almost 300,000 refugees have crossed into Albania since the conflict began, placing considerable strain on local resources and aid agencies.
Up to 20,000 refugees who apparently vanished overnight have now been traced to southern Albania.
Meanwhile, Yugoslav President Slobodan Milosevic has reportedly offered to hand back three American soldiers through Cyprus as a gesture of goodwill.
The speaker of the Cypriot parliament, Spyros Kyprianou, said he will travel to Belgrade on Thursday in an effort to secure the release of soldiers captured by Yugoslav forces last week.
But Nato has said the soldiers' release must be unconditional.
