Explosions rocked the outskirts of a Serb village in the American sector of eastern Kosovo Tuesday evening, killing two people and injuring four, NATO said.
Eight to 10 blasts occurred near Donje Budrige, officials said. Officials had no indication whether the victims were Serbs or ethnic Albanians.
The private Beta news agency in Belgrade said U.S. helicopters hovered over the area after the attack, and angry villagers blocked the roads to demand better protection by American forces.
The explosions occurred one day after Russian soldiers patrolling in the American sector shot to death three Serbs after they disregarded orders to stop beating two wounded Albanians and instead opened fire on the peacekeepers.
These incidents have raised tensions before the scheduled Sept. 19 demilitarization of the rebel Kosovo Liberation Army.
