The protesters briefly blocked a highway connecting Georgia to Armenia before police dispersed the rally.
Georgia's Rustavi-2 television says security officers assaulted two Azerbaijani reporters who were covering the protest, beating them up, and seizing their equipment. Other reports say up to 15 demonstrators were detained.
Kvemo Kartli is a predominantly Azeri region that borders Azerbaijan. The demonstrators are demanding that they and ethnic Georgians be given equal access to land.
