Armenia and Azerbaijan are blaming each other for the latest fighting along their border.
Dozens of soldiers from both sides were killed on Tuesday.
Armenia has accused its neighbour of sending soldiers across the border, and shelling military positions around several cities.
Azerbaijan denies this, saying it was responding to a build-up of landmines and weapons.
Tension between the former Soviet republics largely stems from a standoff over the contested Nagorno-Karabakh region.
Can major regional powers, including Russia and Turkey, prevent another war?
