ITAR-TASS, Russia Saturday 11:32 AM GMT Azerbaijan 220 times violates ceasefire in Karabakh - Armenian ministry YEREVAN August 19 Armenia’s Defense Ministry claimed Azerbaijan had violated ceasefire in the area of Karabakh conflict 220 times. YEREVAN, August 19. /TASS/. Armenia’s Defense Ministry claimed Azerbaijan had violated ceasefire in the area of Karabakh conflict 220 times. "Between August 13 and 19, along the line of engagement between the armed forces of Nagorno Karabakh and Azerbaijan the enemy continued violating ceasefire," the Armenian Defense Ministry said in a statement on Saturday, referring to date of the Nagorno-Karabakh armed forces. "The ceasefire was violated more than 220 times, as the military made more than 3,300 shots." The situation along the contact line of conflicting sides in Nagorno-Karabakh deteriorated dramatically overnight to April 2, 2016 when fierce clashes began. The parties to the conflict accused each other of violating the truce. On April 5, a ceasefire agreement was reached with Russia’s mediation. Since then, the parties to the conflict have been reporting about periodic exchanges of fire in the region. In a trilateral statement adopted on June 20, 2016, following a summit of Russian, Armenian and Azerbaijani presidents in St. Petersburg, the sides confirmed their commitment to the normalization of the situation along the disengagement line in Nagorno-Karabakh. The Nagorno-Karabakh conflict The highland region of Nagorno-Karabakh (Mountainous Karabakh) is a mostly Armenian-populated enclave inside the sovereign territory of Azerbaijan. It was the first zone of inter-ethnic tensions and violence to appear on the map of the former USSR. Even almost a quarter of a century after the breakup of the Soviet Union, Karabakh remains a so-called 'frozen conflict' on the post-Soviet space, as the region is the subject of a dispute between Azerbaijan and the local Armenian population that draws on strong support from fellow-countrymen in neighboring Armenia. In 1988, hostilities broke out there between the forces reporting to the government in Baku and Armenian residents, which resulted in the region's de facto independence. In 1994, a ceasefire was reached but the relations between Azerbaijan and Armenia remain strained ever since then. Russia, France and the U.S. co-chair the Minsk Group of the Organization for Security and Cooperation in Europe, which attempts to broker an end to hostilities and the conflict.
