Somebody is making bad munitions

From Caucasian Knot 

Azerbaijani combat engineers report defusing 18,600 unexploded bombs in a 46,000-acre area following the end of last fall’s short war with Armenia. That works out to one live bomb in every 2.4 acres cleared. Azerbaijani authorities also say “106 citizens of Azerbaijani were blown up on mines” after the fighting ended.

Armenia receives 94 percent of its military hardware from Russia, while Azerbaijani gets the bulk of its weapons from Israel. Bombs refers to mortar and artillery rounds as well as ordnance delivered by aircraft.
