During the early 1990s Azerbaijan lost control over the territory of Nagorno-Karabakh and seven regions as a result of a conflict with the Armenian population of the region and Armenia.
Ceasefire between Armenia and the self-proclaimed Nagorno-Karabakh Republic on one side and Azerbaijan on the other side was established in May 1994.
Presently, negotiations are mediated by the OSCE Minsk Group, which was set up in 1992 to find ways to peacefully resolve the Nagorno-Karabakh conflict. The group includes Azerbaijan, Armenia, Belarus, Germany, Italy, Sweden, Finland and Turkey. The group is co-chaired by Russia, France and the United States.
Azerbaijan does not consider the self-proclaimed republic of Nagorno-Karabakh a party to the conflict and refuses to conduct negotiations with it.

Clashes on the border began on July 12 and continued through July 15 in the adjacent regions - Tovuz (Azerbaijan) and Tavush (Armenia), which also border on Georgia and are located hundreds of kilometers from Nagorno-Karabakh, where the situation remained calm.
