(Belgrade, Serbia-Montenegro-AP) -- The Serbian government is meeting in emergency session after its leader was assassinated. Police sources say Prime Minister Zoran Djindjic (JIHN'-jihch) was ambushed by gunmen outside his government complex in Belgrade. He was reportedly shot in the abdomen and back, and died after arriving at the hospital. His sobbing wife was seen being led away from the hospital building. Witnesses say two people have been arrested, and that one of them was injured in the shooting. The government building where the ambush occurred has been sealed off -- and all bus, rail and plane traffic from Belgrade was halted as police cast a wide net for anyone connected to the assassination. Djindjic had many enemies because of his pro-reformist and Western stands.
