US ambassador to Azerbaijan Mark Libby commented on Baku’s latest provocation on the Armenian-Azerbaijani border.

The American diplomat told the local media that the tension on the border is cause for concern, APA reports.

"Such incidents show that the situation is likely to worsen. We call on the parties to refrain from escalation and try to start dialogue," the US envoy emphasized.

Also, the diplomat underscored that the US has always recognized the territorial integrity of Armenia and Azerbaijan.

"We did not recognize any institution in the territory of Azerbaijan, and we voted for the UN resolutions on the territorial integrity of Azerbaijan," Libby said.
