US builds up Kosovo forces
Nato troops are already based in Macedonia
The United States has ordered more than 50 extra aircraft to move to Europe for possible air strikes against Serbia if the current Kosovo peace talks fail.
The deployment brings to 260 the number of US aircraft which could be used in Nato air strikes against Serbian targets. The forces are on 48-hour alert.
The Serbs oppose the deployment of a Nato-led military force to implement any peace deal as they say it would deny their sovereignty.
The move followed fresh US warnings against Serbia. State Department spokesman James Foley said Yugoslav President Slobodan Milosevic had only a few days "to see the light".
The Clinton administration has warned that the Serbs could face swift and severe consequences if their position does not change by noon on Saturday - the deadline for the end of the peace talks.
Diplomats say the chances of agreement are less than 50%. Aside from the Serbs' intransigence, the ethnic Albanians - who account for 90% of Kosovo's population - have rejected international calls to disarm.
After meeting the international negotiators and both delegations at the talks at Rambouillet near Paris, the two men said there was some movement.
However BBC Diplomatic Correspondent Barnaby Mason said progress seemed to be confined to the political parts of the proposed peace settlement - dealing with the constitution and institutions of a self-governing Kosovo during an interim period of three years.
He said instructions had clearly been given to the Serb delegation from Belgrade and the Serb delegation was engaged in the negotiations.
One of the leaders of the Serb delegation, Nikola Sainovic, flew home this week to confer with President Milosevic. Together with a brief visit by the chief American negotiator to Belgrade, it confirmed the importance of Mr Milosevic's involvement, despite Kosovo Albanian displeasure at negotiations taking place elsewhere.
Conference sources said the two delegations at Rambouillet did meet for five minutes on Wednesday, though a joint negotiating session did not take place.
In a separate development, Nato Secretary-General Javier Solana is due to visit the Former Yugoslav Republic of Macedonia on Thursday to hold talks over its part in the Nato plan to end the conflict.
