Kosovo Albanians said today they would start immediate talks with Western backers about an independence declaration, but Russia said unilateral recognition could trigger a "chain reaction" of problems around the world.
With a UN deadline for agreement on Kosovo's future expiring today, Serbia said it would demand an International Court of Justice ruling if its breakaway province went ahead and declared independence.
Meanwhile in Brussels, EU ministers said they had come closer to agreeing a common position on independence for the Serbian province.
"From today, Kosovo begins consultations with key international partners to coordinate the next steps to a declaration of independence," Skender Hyseni, spokesman of Kosovo's negotiating team with Serbia, said in Pristina.
"Kosovo and the people of Kosovo urgently need clarity on their future ... The institutions of Kosovo will deliver that clarity very soon."
He said a declaration would come "much earlier than May", referring to one rumoured timeframe. In Washington, the State Department echoed the urgency and reaffirmed it backed moves to help Kosovo towards supervised independence with provisions to protect its Serb minority.
"The people of Kosovo and the region urgently need clarity about their future," a Department spokesman said. "UN must decide" Serbia, firmly against independence, insisted that only the United Nations had the authority to determine Kosovo's future.
"That process belongs to the U.N. Security Council and to all countries that are members of the UN, not to the EU," Deputy Prime Minister Bozidar Djelic said on the sidelines of a conference in Belgrade about EU accession.
President Boris Tadic told state television that Serbia would urgently ask the Security Council to request an opinion from the International Court of Justice, "asking whether the independence of Kosovo would be legal".
Even if the divided Council agreed to send such a request, the Court could take years to issue an opinion, which would in any case be advisory and non-binding.
Kosovo, which has a 90-per cent Albanian majority, has been in legal limbo under UN administration since NATO bombing in 1999 pushed out Serbian forces to end ethnic cleansing.
Serbia's main ally on the issue is Russia, able to veto any recognition of Kosovo by the UN Security Council. Russia's foreign minister, Sergei Lavrov, said in Nicosia that a unilateral declaration of independence would "create a chain reaction throughout the Balkans and other areas of the world".
