Azerbaijan said on Sunday it had established a checkpoint on the only land route to the contested region of Nagorno-Karabakh, a step that was followed by claims of border shootings by both Azeri and Armenian forces.
Nagorno-Karabakh is internationally recognised as part of Azerbaijan, but its 120,000 inhabitants are predominantly ethnic Armenians and it broke away from Baku in a war in the early 1990s.
Azerbaijan said it had established a checkpoint on the road leading to Karabakh, a step it said was essential due to what it cast as Armenia's use of the road to transport weapons.
