Lord Owen and Cyrus Vance, joint chairmen of the talks in Geneva, will tomorrow ask the UN to impose a solution on the warring sides. The deal drawn up by the negotiators on behalf of the UN and the European Community divides the country into 10 provinces.
As the five months of peace talks ended in deadlock, Sarajevo, the Bosnian capital, came under intense bombardment from Serbian guns. Outside the presidency building, a shell killed two people.
In Geneva, Lord Owen said: 'Time is not on our side and we cannot go on here. UN personnel have lost their lives fighting for these issues. We have brought it deliberately to a crunch.'
