rocks near one of the blocked bridges KFOR intervened to stop the violence. The previous night had passed without incident in most of northern Kosovo, except for a minor incident near Zupče and Cabra with shots fired in the area because of an increased police presence in Mitrovica. After the shooting, Kosovar Serbs set-up another barricade next to an existing encampment in Zupče on the road from Mitrovica to Ribarici; gravel was dumped across both lanes of the road leading to the southern part of Mitrovica. The next day there were clashes at the roadblocks after they were reinforced with more Serb protesters and Kosovo Police officers. KFOR helicopters dropped hundreds of leaflets urging the Serbs to end their roadblocks on 29 September.

According to him, both crossings were technically ready to be fully operational, but the barricades erected on nearby roads prevented the gates from being utilised. Pipe bomb explosions injured four soldiers on 27 September. NATO spokesman Kai Gudenoge then said that German KFOR troops were forced to fire rubber bullets and tear gas in self-defence against Kosovan Serb protesters after being attacked at administrative border crossing Gate 1 following an attempt by Kosovar Serbs to erect a new roadblock after KFOR blocked an alternative road to Serbia proper. Five protesters were arrested. Hospital officials in northern Kosovo said seven Serb protesters were wounded from gunfire, which erupted in the afternoon in Jarinje. The head of Mitrovica hospital, Milan Jakovljevic, said the wounded had been brought to his hospital for medical treatment, adding: "We can't say if anyone has life threatening injures at this moment, since
