Mr Sljivancanin's arrest triggered violent clashes in Belgrade

Tribunal spokesman Jim Landale said Veselin Sljivancanin - who was arrested in Serbia two weeks ago - arrived from Belgrade late on Tuesday.

Mr Sljivancanin is one of the so-called Vukovar Three indicted for the mass killings of non-Serbs near the eastern town of Vukovar during the war in Croatia in 1991-1995.

The other two suspects - General Mile Mrskic and Captain Miroslav Radic - have already surrendered to the court.

In another development, the Serbian parliament voted on Tuesday to set up a special court to try war crimes suspects.

The BBC's Geraldine Coughlan says there is speculation that the first trial could deal with the Vukovar killings.

Belgrade standoff

Mr Sljivancanin - alongside the two other suspects - is charged with removing at least 200 patients and civilians from a hospital in Vukovar, after it fell to Yugoslav troops.

It is alleged that they were then taken to a nearby pig farm, executed and buried in a mass grave.

The three suspects allegedly supervised the execution and burial in a mass grave.

Mr Sljivancanin was picked up by police after a 10-hour standoff outside his Belgrade house following violent clashes with hundreds of his supporters.

The arrest came just days before the United States threatened to suspend its financial aid unless Serbia complied with the Hague tribunal.

It leaves former Bosnian Serb President Radovan Karadzic and army commander Ratko Mladic as the two remaining top fugitives for war crimes during the break-up of Yugoslavia.
