The war crimes trial of former Bosnian Serb commander Ratko Mladic was suspended until further notice Thursday over the prosecution's failure to disclose some evidence against Mladic, court spokeswoman Nerma Jelacic said.
The abrupt suspension came only a day after the long-awaited trial began.
Prosecutors had been planning to focus Thursday on the massacre of up to 8,000 Muslim men and boys at Srebrenica, for which they accuse Mladic of responsibility.
But the defense called for a halt to the trial after it found that the prosecution had not shown it all the evidence against Mladic. Under court rules, the defense has a right to study prosecution evidence before a trial begins.
