Gunfire has been reported along the Kyrgyz-Tajik border.
Kyrgyzstan's State Border Guard Service said on November 28 that a group of Tajik border guards entered a disputed area along the border in the southern Batken region in the morning and shot three times into the air.
The Kyrgyz side fired once into the air in response, officials said.
No casualties were reported.
Border officials from the two countries held extraordinary discussions regarding the shootings and decided to investigate the incident.
According to previous agreements, both sides must keep several dozen meters away from the disputed area.
Hundreds of kilometers of borders in Central Asia have been disputed since the collapse of the Soviet Union in 1991.
Shootings, blockades, and clashes have occurred frequently in the areas close to the disputed border segments.
