In a statement, the ministry said the soldier, Hanoglan Halilov, got killed in the occupied Karabakh region when Armenian forces opened artillery fire on Azerbaijani emplacements.
Clashes in the Upper Karabakh region, which pro-Armenian militia occupied in 1993, are nothing new.
In April, 2016, more than 270 military personnel lost their lives in the worst-ever breach of a 1994 treaty between the sides, according to the Azerbaijani Defense Ministry.
Three UN Security Council Resolutions (853, 874 and 884), and United Nations General Assembly Resolutions 19/13 and 57/298 refer to Karabakh as part of Azerbaijan. The Parliamentary Assembly of the Council of Europe refers to the region as being occupied by Armenian forces.
