BAKU -- Azerbaijan says one of its army officers has been shot dead near the border of the breakaway Nagorno-Karabakh region.
Defense Ministry officials told RFE/RL on April 9 that Lieutenant Sahriyar Mammadov was killed by Armenian forces based in Nagorno-Karabakh.
The officials said Armenian troops "violated the cease-fire agreement" late on April 8 near the Aqdam district, which is a buffer zone.
There was no immediate response from the Armenian side.
Nagorno-Karabakh is a mostly ethnic-Armenian-populated region inside Azerbaijani territory.
Armenia, which controls Nagorno-Karabakh and several surrounding districts, has been locked in conflict with Azerbaijan for more than two decades over the enclave.
After going to war, a truce was signed in 1994, but there is still sporadic violence.
Years of internationally mediated talks have failed to resolve the conflict.
