On 16 February near the border town of Podujevo seven Serb civilians were killed after Niš-Ekspres bus with refugees from Kosovo was blown up by the UÇPMB.

The UÇPMB clashed with the Serbian security forces began in July 2000 and were aimed at conquering the communication Bujanovac-Gjilan and taking over the villages of the municipality of Bujanovac.

The fighting was intensified in November 2000, when the police, under the influence of a threefold strength of the UÇPMB, withdrew from the security checkpoints that were fought, occupying defensive positions closer to Bujanovac.

Around 17:00 the withdrawal of the people from the crisis zones was terminated because it was found that at the Dobrosin point there was a mortar of 60 millimeter, a sniper and automatic rifle, two combat ammunition kits, 6 inductor phones and more.

Later, in the period between 21:45 and 23:15, the rebels carried out attacks on the police in the village of Djordjevac from mortars, hand grenades (fired 20–30 mines) and infantry weapons.
