Serbia Arrests 2 Key Suspects

Two key suspects have been arrested in the assassination of Prime Minister Zoran Djindjic, a senior police official said Saturday.

The official, who spoke on condition of anonymity, refused to give details about the suspects beyond saying they were "very important."

More than 2,700 suspects have been rounded up since Djindjic was killed in a sniper ambush on March 12.

Serbian Justice Minister Vladan Batic said about 1,000 are still in custody, including several state security and police officials. But the top suspects, including at least three assassins, were still believed to be at large.

The Serbian government has blamed the assassination on the underworld Zemun Clan, a network of mobsters, paramilitary and former security service figures linked to remnants of former Slobodan Milosevic's regime.

Investigators have uncovered "illegal jails" in several summer houses in the north of the country where "mobsters tortured kidnapped people," the senior police official told The Associated Press.

"We discovered a wide array of military weaponry, handcuffs and chains there," he said.

Milosevic is now standing trial at the Netherlands-based U.N. war crimes tribunal for genocide and other war crimes committed in the 1990s Balkan wars. Djindjic played a crucial role in his extradition.
