SARAJEVO, Bosnia-Herzegovina (AP)—A new cease-fire accord failed to curb fighting on Wednesday in central and southwestern Bosnia, where civilians appeared to be bearing the brunt of the attacks.

‘‘The aggression continues with the same intensity,’‘ said Stjepan Siber, deputy commander of Bosnia’s Muslim-led government army.

Presidents Alija Izetbegovic of Bosnia and Franjo Tudjman of Croatia signed an accord Tuesday in Geneva calling for fighting to stop ‘‘immediately and by no later than’‘ Saturday.

Serbs, who control 70 percent of Bosnian territory, were not party to the agreement.

Several previous agreements have failed to halt the bloodshed, and Siber held out little hope that fighting between Croat and government forces would ease before Saturday, if then.

State-run Bosnian radio reported heavy shelling around Mostar, the major city in southwestern Bosnia, where 55,000 Muslims are under siege by Croats. U.N. officials say 10 to 15 people were dying daily from shelling and sniper fire.

Croats, meanwhile, accused government soldiers of murdering 29 civilians on Tuesday in the tiny village of Uzdol, near Prozor about 30 miles north of Mostar.

A spokesman for the self-declared Croatian government in Bosnia, Toni Vucic, said of 29 villagers killed in Uzdol, 18 were men, eight women and three children—two girls, ages 12 and 13, and a 10-year-old boy.

The Croats said 11 Muslim soldiers were killed by Croat soldiers as they fled Uzdol. The Croats listed eight dead among their troops.

Associated Press photographer Laurent Rebours, who visited Prozor and the Uzdol after the killings, said about half the houses in the village, once home to 583 people, were burned down.

He said there were six corpses still in the village on Wednesday, including a dead man lying in a courtyard with a chest wound. His wife’s body was on the dining room floor inside their house, where she apparently had been felled by a spray of bullets fired through a window.

The bodies of another elderly couple were found huddled together under blankets in a barn, where they apparently tried to hide.

‘‘I think they had no time to understand what happened,’‘ Rebours said. ‘‘It seemed is if they had heard noise, went outside and then were killed.’‘

British U.N. peacekeepers reportedly were heading to the village to investigate.

At the outset of Bosnia’s war, Croats and government forces fought together against heavily armed Bosnian Serbs who rebelled over a decision to secede from Yugoslavia.

But the alliance collapsed in bitter fighting over central Bosnian territory. There is evidence of murder and other atrocities against civilians by both sides.

Sarajevo, Bosnia’s besieged capital, was relative calm on Wednesday during a visit by Russian Foreign Minister Andrei Kozyrev, who is trying to get three-way Geneva peace negotiations started again.

Talks on a plan to divide Bosnia among its three warring factions ended abruptly Sept. 1, when Izetbegovic objected to what he said was an unfair deal that rewarded Serb aggression.

All sides have expressed willingness to resume talks, but no date has been set.

‘‘I am pleased that there is no shooting, no shelling (in Sarajevo),’‘ Kozyrev said after meeting with government officials.

‘‘We will urge all parties to seize this opportunity,’‘ he said. ‘‘My feeling is that there is enough goodwill on all sides.’‘

In Croatia, fighting appeared to ease up on Wednesday between Croats and the Serb minority.

The latest warfare started last Thursday when the Croatian army captured three Serb-held villages near Gospic in the country’s southwestern arm.

The Yugoslav news agency Tanjug said the Croats had begun to withdraw from two of the villages under a U.N.-brokered cease-fire calling for about 500 U.N. peacekeepers to move into the area.

In New York, meanwhile, the U.N. General Assembly elected eight justices—including a U.S. law professor—to a planned international war crimes court for former Yugoslavia.

Three more justices were to be elected Thursday to the tribunal, which will hear cases involving Serb, Muslim and Croat crimes in wars in Croatia and Bosnia-Herzegovina since 1991.

One justice was Gabrielle Kirk McDonald, a U.S. law professor and former U.S. District Court and U.S. Circuit Court of Appeals judge. A date for the court to open has not been set.
