On that day, Serbian police officers invaded the predominantly Albanian village of Dobrosin on the border with Kosovo.

The village was part of the "demilitarized zone" following the Kosovo War and Kumanovo Agreement in 1999.

[3][4][5] From 21-27 November the LAPMB committed synchronized attacks on the Dobrosin security checkpoint, and on the positions of the police on the corners of Devojačka Čuka and Osoje.

Due to the Heavy fighting, members of the Special Police Units from Gornji Milanovac were forced to withdraw to Konculj, Lučane and Bujanovac.

[6][7] Police withdrawal was hampered and slowed down due to lack of knowledge of the terrain.
