Kyrgyzstan announced, on Friday, that three citizens were killed after Uzbek troops opened fire at the disputed frontier of the two Central Asian countries.
"Without regaining consciousness, they died from their gunshot wounds," the Kyrgyz national security committee said in a statement, adding that it had taken place on Thursday.
Reports asserted that it was the most serious incident to occur at Kyrgyzstan and Uzbekistan's frontier in recent years.
The statement revealed that the representatives of both the border services had made contact immediately and agreed to conduct an investigation, noting that they were due to meet on Friday.
Kyrgyzstan did not clarify whether the dead were civilians or border troops.
Smuggling is a common problem in the region while border communities also clash regularly over land for grazing animals and water resources.
Uzbekistan's border service could not be reached for comment.
