Bosnian Serbs Under Assault

Government forces who have handed Bosnian Serbs their worst defeats in 2 1/2 years of war pushed ahead Monday with assaults on a supply route near Sarajevo and on Serb-held towns in the northwest.

Serbs claimed to have blunted the offensives and promised intense fighting to regain lost territory.

Whether the Serbs have the troops, materiel and morale to rebound could determine whether the government’s offensive will decisively change the course of the war.

Serbs said the government attack on their supply road, near Trnovo, was backed by an estimated 8,000 troops who traveled to the front from besieged Sarajevo through a tunnel under the airport.

U.N. peacekeepers confirmed that government forces pushed back Serbian troops in northwestern Bosnia. Bosnia’s official radio reported that government troops took 12 square miles of territory, closing in on the towns of Bosanska Krupa and Bosanski Petrovac.
