The ministry also released a video of the attack on the Armenian frontline.
The two countries remain in dispute over the occupied Karabakh region.
Clashes in the region, which pro-Armenian militia took over 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.
