THE HAGUE, Netherlands (AP) – The Yugoslav war crimes tribunal convicted a wartime leader of Croatia’s rebel Serbs of murder, torture and persecution Tuesday and sentenced him to 35 years in prison for a brutal ethnic cleansing campaign of non-Serbs in Croatia.

Judges said Milan Martic, 52, was responsible for hundreds of murders from 1991 when Serbs in the Krajina region of northeastern Croatia rebelled and set up a breakaway ministate until 1995 when Croatian forces recaptured the area.

He also was convicted of ordering two days of indiscriminate cluster bomb shelling of the Croatian capital, Zagreb, in May 1995 that killed at least seven civilians and injured more than 200.

Most of the crimes were “committed against elderly people, persons held in detention and civilians. The special vulnerability of these victims adds to the gravity of the crimes,” said presiding judge Bakone Moloto.

Martic stood still and showed no emotion as Moloto read out the verdict and his sentence.

The three-judge U.N. panel said Martic was deeply involved in a criminal plot with other Serb leaders including Slobodan Milosevic, General Ratko Mladic and Radovan Karadzic to carve out an ethnically pure “greater Serbia” as Yugoslavia crumbled that would include about one third of Croatia.

“It is clear that Milan Martic endorsed the goal of creating a unified Serb state,” said JUdge Moloto.

Martic was indicted in July 1995, just two months after ordering the shelling of Zagreb.

The indiscriminate attack using rockets loaded with cluster bombs over two days hit buildings including a school, a children’s hospital and the Croatian national theater, said Moloto. In media interviews, Martic admitted ordering the shelling to retaliate against Croatian attacks on Serbs and warn against further attacks, Judge Moloto said.

Describing attacks on Croat villages by Martic’s forces, Moloto said that after the initial military push by Serb forces subsided, “acts of killing and violence were committed against the civilian non-Serb population who did not manage to flee. Houses, churches and property were destroyed and widespread looting was carried out.”

Martic turned himself into the U.N. court in May 2002 and pleaded not guilty to all 19 charges of war crimes and crimes against humanity.

He was convicted Tuesday of 16 counts and acquitted of the charge of extermination, saying the number of deaths involved did not justify the charge. Judges dropped two other charges, saying they were covered by another charge in the indictment.

Prosecutors called 45 witnesses to testify against Martic, including another Croatian Serb Milan Babic, who was sentenced to 13 years for his involvement in the atrocities and later committed suicide in the tribunal’s detention unit after testifying against Milosevic.

The Croatian general, Ante Gotovina, who drove the rebel Serbs out of the Krajina in 1995 also is on trial at the U.N. court for offenses committed in Operation Storm that successfully reclaimed the region.
