UN security Council members have expressed shock at a deadly bomb attack on a bus bringing Serbs into north Kosovo. They have called for a quick investigation to bring those responsible to justice.
Seven Serbs died and dozens of others were injured in the bombing, the second attack on a Serb convoy this week.
The attack, part of a wave of recent attacks on Serbs in Kosovo, was "totally unacceptable and must be reversed", said a statement read by Mr Said Ben Mustapha of Tunisia, president of the 15-nation council.
The statement also called on all of Kosovo's residents "to stand against the violence of extremists working against peace and stability".
Separately, Mr Hans Haekkerup, UN Secretary-General Kofi Annan's special envoy to Kosovo, said the blast "marks a serious blow against the people of Kosovo".
The province has been under UN administration since the NATO bombing campaign that forced the withdrawal of Yugoslav troops and police.
Mr Haekkerup said the attack had targeted a convoy of buses being escorted by peacekeepers just after it crossed over into Kosovo province and was "clearly well planned".
The blast was triggered when the first bus in the convoy hit a trip-wire while crossing a culvert packed with explosives, he said.
"The international community will judge today's tragedy, along with other attacks in recent days, in the harshest possible terms," Mr Haekkerup said.
