Former Bosnian Serb leader Radovan Karadzic has dismissed as myths the alleged two worst atrocities of the 1992-95 Bosnian war.
Mr Karadzic has told his trial at The Hague that Sarajevo, where about 12,000 people died in 44 months, was "not a city under siege" by Bosnian Serb forces.
He also described the 1995 Srebrenica massacre of more than 7,000 Muslim men and boys as being based on "false myths", the BBC reports.
Mr Karadicz said Bosnian Serb gunfire and shelling of Sarajevo was restricted to legitimate targets.
He accused Bosniaks and Croats of turning the city's kindergartens, schools and hospitals into military facilities by setting up command posts and sniper positions there.
He said they had used terror attacks in an attempt to bring NATO and Western countries and troops on their side.
Radovan Karadzic is accused of genocide and war crimes committed during the conflict. He denies all 11 charges.
The trial has been adjourned.
