Vojislav Seselj was expelled Saturday after attending an inauguration party for new Bosnian Serb president and

fellow nationalist Nikola Poplasen in the Serb-run part of Bosnia.

An angry Seselj told reporters that his expulsion was ``brutality showed by the occupying forces.''

``I will go to Bosnia again, when I wish to,'' he said.

NATO peacekeepers in armored cars surrounded the hotel in Banja Luka where the reception was held and told

Poplasen that Seselj had to leave, citing orders from the office of the U.N. high representative in Bosnia, the top

foreign authority overseeing the country's postwar development.

Seselj was back in Belgrade on Sunday, where he blasted ``the veiled form of occupation which basically does not

differ from Hitler's.''

Seselj, a former paramilitary leader in Serb rebellions in Bosnia and Croatia, heads the ultranationalist Serbian

Radical Party. Poplasen is head of the sister Serb Radical Party in Bosnia.

Seselj said that even though he thinks the expulsion contradicts the 1995 Dayton peace agreement guaranteeing

freedom of movement, he agreed to leave on Saturday to spare Poplasen from more trouble.

Meanwhile, newspapers reported Sunday that Bosnian President Alija Izetbegovic warned again he will resign if

international officials award control of the disputed town of Brcko to Bosnian Serbs.

International arbitrators have three times postponed a decision on the strategic northern town for fear of wrecking

Bosnia's tense stability. Both sides have threatened to resume fighting if control goes to the other half.

No date is scheduled for a decision, but it is expected later this year or early next year.

Brcko, now supervised by American Robert Farrand, is the only territorial question left undecided by the 1995

Dayton agreement.
