Orthodox churches, especially around Tuzla, have been destroyed or damaged by Muslim-led Bosnian forces.

Mr. Perry and his senior advisers say beefing up the Muslim-led Bosnian forces could be accomplished within a year.

Last month Muslim-led Bosnian forces counterattacked and took some land to the west of town.

During the 1992-95 conflict in Bosnia, some of its leaders fought with the Muslim-led forces against the Serbs.

But scrambling to circumvent an arms embargo whose initial effect was to perpetuate their vulnerability, the Muslim-led Bosnian forces now have some means of hitting back.

President Dobrica Cosic of Yugoslavia complained today that "200 were killed" by Muslim-led forces on the Bosnian side of the border.

Most of Sarajevo is held by the Muslim-led forces of the Bosnian Government.

The guns are a type that the Bosnian Serbs used to devastating effect against the Muslim-led forces during the Bosnian war.

During the war, Iran was a major supplier of weapons to the Muslim-led forces.

But it appears just as likely that the Muslim-led Bosnian forces will want to fight on.
