Sarajevo, Wednesday

MUSLIMS and Serbs blasted each other with mortars and artillery in

battles across Bosnia today as a European plan for the United Nations to

monitor combatants' heavy weapons ran into unexpected trouble.

Worked out in peace talks brokered by the European Community, the plan

provided for heavy weapons, from mortars and rocket launchers to

artillery, to be placed under UN supervision.

But in an extraordinary turn to the Bosnian drama being played out on

the battlefronts and in diplomatic corridors, UN Secretary-General

Boutros Boutros-Ghali rejected the plan -- which had already been

endorsed by the UN Security Council.

The UN chief's cold shoulder on the idea appeared to set back the

peace efforts of Lord Carrington, the EC's chief negotiator on

Yugoslavia, who chaired the London talks which produced the agreement.

Although the truce accord was ignored from the outset, it had provided

a glimmer of hope for an eventual breakthrough.

Despite sporadic shelling and machine-gun fire throughout the day, 15

aircraft flew into Sarajevo airport to deliver emergency supplies for

380,000 people trapped by almost four months of Serbian siege.

Elsewhere in Bosnia-Herzegovina, fighting continued unabated.

Croatian radio said more than 50 people were killed or wounded

overnight in heavy shelling by Serb rebels around the besieged town of

Gorazde, south-east of Sarajevo.

There was no independent confirmation of the figure but the radio said

more than 500 shells were fired at surrounding villages and at Gorazde,

where 70,000 residents, mostly-Muslim but also Serb, are trapped.

Gorazde's mayor said the town had enough food for just 48 hours and

might have to surrender to Serb forces.

During the night, battles raged in Sarajevo for more than two hours

before tapering off into sporadic exchanges. UN spokesman Mik Magnuson

said 300 to 400 mortar rounds were fired in one hour.

Camp Beaver, where Canadians in a UN peace-keeping force have set up

base in the west of the city, was hit by several mortar rounds, damaging

buildings and vehicles.

Fighting in Sarajevo and around Bosnia has picked up since the

EC-brokered ceasefire was signed last week. It had been due to take

effect on Sunday.

Lord Carrington and the UN commander in Sarajevo, General Lewis

MacKenzie, blamed all parties -- Serbs, Muslims and Croats -- for

violating the ceasefire. It was the 39th arranged by the EC.

More than 7500 people have been killed in fighting since Bosnia's

Muslims and Croats voted in March to split from Yugoslavia and form an

independent state. That move sparked a rebellion by Bosnia's Serbs,

about 31% of the 4.3 million population.

The latest round of fighting has left those sent by the international

community to try to halt the bloodshed openly pessimistic.

MacKenzie spoke yesterday of a ''downward spiral'' in the civil war

and said combatants shrink from nothing, not even shelling their own

people, to win world sympathy.

''We have evidence that both sides shell themselves in order to create

a particular image. I got so frustrated about this a month ago that I

said to both sides: 'If you'll stop shelling yourselves, maybe we'll

have peace around here','' he said.
