Radovan Karadzic asked the International Criminal Tribunal for the former Yugoslavia (ICTY) on Monday to subpoena Miroslav Tudjman, the former head of Croatian intelligence services, to give evidence in his trial.

The former political leader of Bosnian Serbs claims Miroslav Tudjman, son of former Croatian president Franjo Tudjman, has proof that weapons were “smuggled to the army of Bosnian Muslims by Iran and other Muslim countries via Croatia" during the Bosnian war (1992-1995), Mr. Karadzic said in a query.

"As director of the Croatian secret service, Mr. Tudjman is particularly well placed to reveal what documents exist which reflect the agreement with Iran to ship arms to the Bosnian Muslims," says Mr Karadzic which indicates that Mr. Tudjman refused to be questioned by his lawyer.

Karadzic alleges this happened with the acquiescence of the United States and other United Nations members, and says humanitarian convoys were used to smuggle the arms into Bosnia.

"An important allegation against Dr Karadzic is that he impeded the delivery of humanitarian assistance in Bosnia," says the motion.

"Mr Tudjman's evidence is likely to demonstrate that there was a good reason for the Bosnian Serbs' concern over the contents of those convoys", it states.

Radovan Karadzic (65) is accused of 11 charges of war crimes, crimes against humanity and genocide during the Bosnian war (1992-1995), that left 100,000 dead and 2.2 million displaced.
