From 1988 to 1994, Azerbaijan was engaged in an armed conflict with its neighbor Armenia and armed forces of the territory of Nagorno-Karabakh. A ceasefire was negotiated in 1994, but a peace agreement is still underway. During the conflict, both sides used landmines. Forces from both Armenia and the self-declared Republic of Nagorno-Karabakh currently occupy about 20 percent of land within Azerbaijan, making demining difficult in those areas.
