THE HAGUE — The Yugoslav war crimes tribunal acquitted former Bosnian Serb leader Radovan Karadzic of one charge of genocide Thursday, but upheld 10 other war-crime counts related to atrocities in Bosnia’s bloody war.

While the decision was a setback for prosecutors and angered survivors in Bosnia, the 10 pending charges against Karadzic include another genocide count covering his alleged involvement in the 1995 Srebrenica massacre of 8,000 Muslim men and boys.

The charge that was dismissed Thursday covered the mass killings, expulsions, and persecution by Serb forces of Muslims and Croats from Bosnian towns early in the country’s 1992-95 war, which left 100,000 dead.

Presiding Judge Oh-Gon Kwon said prosecutors did not provide enough evidence to “be capable of supporting a conviction of genocide in the [Bosnian] municipalities.”

At the halfway stage of Karazdic’s long-running trial, judges said there was enough evidence to uphold charges including murder and persecution in the early stages of the war, but the killings did not rise to the level of genocide.

Prosecutors finished presenting their evidence in May, and earlier this month Karadzic asked judges to dismiss all 11 counts, saying prosecutors had failed to prove their case.

Karadzic’s lawyer, Peter Robinson, welcomed Thursday’s rejection of the genocide charge.

“Dr. Karadzic and myself both thought it was a courageous decision of the trial chamber to say at this stage of the case that there was no genocide in the municipalities in Bosnia in 1992,” Robinson said outside the court. “But I do expect that the prosecution will want to appeal this decision.”

Prosecutors had no immediate reaction.

But survivors of the Bosnian war said the decision could set back any reconciliation.
