Armenia says it will retaliate for the weekend killings of two ethnic Armenian soldiers by Azeri snipers who fired into a disputed breakaway enclave.
Nagorno-Karabakh is a mountainous enclave within the Caspian Sea nation of Azerbaijan, but since the end of a six-year separatist war in 1994 it has been under the control of Armenian troops and ethnic Armenian forces.
Violations of the 1994 cease-fire have been frequent, and Armenian authorities said two servicemen from Nagorno-Karabakh were killed Sunday and Saturday.
Armenia's Defense Ministry spokesman David Karapetian said Monday the retaliation for the soldiers' deaths will be "disproportionate."
His Azeri counterpart, Teymur Abdullayev, said a shootout at the border was provoked by Armenians.
