BELGRADE, Yugoslavia (AP) _ In the wake of a fight between three anti-government students and employees of President Slobodan Milosevic's son, the three students have been arrested on charges they tried to kill the younger Milosevic's associates, the leader of an anti-government organization said Wednesday.

Dejan Randjic, head of the anti-Milosevic students' group Otpor, or Resistance, said the three _ all Otpor members _ were beaten up Sunday evening at an outdoor cafe by employees of the ``Madonna'' disco club, owned by Milosevic's son, Marko. The incident occurred in the Milosevic family hometown of Pozarevac, 50 miles east of the capital, Belgrade.

The chain of events leading up to the fight at the cafe remained unclear, but Momcilo Veljkovic, one of those arrested, claimed Marko Milosevic's associates provoked one of the students. Veljkovic told the Belgrade-based Beta news agency that when he tried to persuade the Milosevic associates to let his colleague be, they hit him on the head. In the struggle that followed, Veljkovic said he grabbed a gun from one of the assailants and fought back.

The fight involved fists and pistol butts, with dozens gathering around to watch, some joining the brawl. There were conflicting reports on whether a gun went off once and who fired it.

Veljkovic, who spoke shortly before his arrest, and two others from Otpor were later detained by police and charged with attempted murder.

``The fact that Veljkovic managed to snatch away the pistol he was being beaten with is now being used as pretext to charge the three Otpor members with attempted murder,'' Randjic said. He said all three had been transferred to Belgrade prison from Pozarevac.

A local police statement said the three Otpor members were ``known as persons of delinquent behavior.'' One of the three arrested was transported to a Belgrade clinic, suffering from a broken nose and head injuries, Beta reported.

Yugoslavia's information minister and a high-ranking Communist party official, Ivan Markovic, said that a ``group of hooligans with Otpor's fascist symbol'' were the aggressors. Vukasin Petrovic, another leader of the student group, rejected Markovic's accusations and said that Marko Milosevic and his close associates in this town had ``frequently threatened and assaulted Otpor members'' even before the fight Sunday night.

The back-and-forth accusations also reached the national political level. The opposition Democratic Party issued a statement saying that the ``brutal terror by Marko Milosevic and his circle of associates ... has been going on for months,'' while Milosevic's ruling Socialists said the ``heinous attack by Otpor ... constituted a criminal act by people who daily plot all forms of terrorism, up to the murder of honest citizens and patriots.''
