BOSNIA . . . SKIRMISHES ON BOTH SIDES

Bosnian Serbs fired on Muslims with an antiaircraft gun seized from a U.N. facility. The Serbs were responding to an earlier machine-gun attack by the Bosnian government. Both the Muslims and the Serbs have been giving signs of preparing for a land grab, gathering soldiers north of Sarajevo. Still, says TIME Central Europe Bureau Chief James Graff, "no one thinks that offenses of strategic importance are in the offing right now even though there may be a kilometer won here and a kilometer lost there."
