Special envoys Cyrus Vance for the United Nations and Lord Owen for the European Community continued to talk to all sides in the Bosnia crisis to ensure their participation in a peace conference tomorrow despite moves to oust Yugoslavia from the UN.
Leaders of all three parties to the conflict are due in Geneva Friday for discussions on how to end the fighting.
Some experts argue that toughening of the international stand against Yugoslavia could undermine Prime Minister Milan Panic and his efforts to curb Serbian ambitions.
Meanwhile, BBC television reported yesterday that hundreds of Islamic fighters have entered Bosnia from countries such as Iran and Saudi Arabia to fight alongside Muslim forces. The report from two towns northwest of Sarajevo showed secretly filmed footage of what it said were Islamic fighters giving arms training. The BBC correspondent said Croat troops at checkpoints claim almost 700 fighters have passed through in small groups in recent weeks.
