A statement, agreed in Brussels at a meeting of all 19 Nato foreign ministers said: "Nato's military action will be pursued until President Milosevic accedes to the demands of the international community."

While the ministers were meeting, the UK Ministry of Defence again ruled out the use of Nato ground troops in Yugoslavia.

Earlier, Albania called for Nato intervention after it said Serbian artillery positions attacked an Albanian border village, killing two civilians.

The BBC's Stephen Gibbs: "Nato is again bombing hard"

The Albanian Government, which has handed control of its air space and ports to the alliance commanders, wants Nato to hit Serb artillery that it says is in a position to launch further cross-border assaults.

The Serbs, in turn, accuse Albania of helping terrorists, its term for the Kosovo Liberation Army.

One new Nato country, Hungary, is coming under heavy pressure from Russia in a row over aid.

Hungary has refused to let it enter, because it says that the large quantity of diesel fuel it is carrying could be used by the Yugoslav military.

Russia, which says the convoy is loaded with food and medicines, has warned Hungary that their action could damage relations between the two nations.

The Yugoslav parliament has voted unanimously to join a loose union Belarus and Russia, which has been a strong critic of Nato action.

Ground troops discussed

In London, Ministry of Defence spokesman General Sir Charles Guthrie said Nato planners had discussed sending in ground troops.

The BBC's Paul Reynolds: "The emphasis on the use of ground troops has changed somewhat"

But Sir Charles said there was no current plan to use ground forces.

He said that poor weather on Sunday had hampered missions.

But he added that RAF planes had, for the first time in the campaign, engaged targets through cloud.

The meeting was looking at ways of helping the hundreds of thousands of Kosovo Albanians refugees, as well as a long-term strategy for the stability of the Balkans.

US Secretary of State Madeleine Albright stressed the need to for a political solution.

Mrs Albright told reporters that the blueprint for the future of Kosovo agreed at the Rambouillet peace talks would have to be reconsidered.

And French Defence Minister Alain Richard said it was possible that a future peacekeeping force for Kosovo may not be under Nato's direct control.

At Rambouillet, Yugoslavia rejected all demands for a Nato-led force in Kosovo.

The UK Foreign Minister, Robin Cook, said: "There can be no settlement that does not reverse the programme of ethnic cleansing which President Milosevic has so brutally carried out in Kosovo."

Some Nato governments, including the Italians and Greeks, have concerns about the use of force but are still supporting the camapign.

BBC Defence Correspondent Jonathan Marcus said Nato's main political aim remains the introduction of an international military force to facilitate the return of refugees.

Mrs Albright is due to meet Russian Foreign Minister Igor Ivanov in Oslo on Tuesday in an effort to avoid a further deterioration in relations on the Kosovo issue.

Later in the week, European Union heads of government are also expected to meet to discuss Kosovo.

Serbia weakened

Serbian media reported Nato attacks overnight on Sunday, including an oil refinery in Pancevo, north-east of Belgrade; a car factory in Kragujevac.

Yugoslav officials say Nato bombs killed six civilians, including an 11-month-old baby, in the town of Podujevo in Kosovo.

Nato says the bombing campaign has been successful in slowing the Yugoslav military machine.

And UK prime Minister Tony Blair, writing in the American magazine, Newsweek, implied that Nato's critics are like the politicians who appeased Hitler in the 1930s.

International monitors reported that Serbian shells were still hitting the Albanian side of the border on Sunday.

The Albanian authorities earlier reported two Albanian civilians killed and 12 others hurt when Serbian bombs hit the town of Tropoja and nearby Padesh.

And Montenegro, Serbia's junior partner in the Yugoslav Federation, repeated warnings that the Yugoslav army might be planning a coup against its more pro-Western government.
