The governments of Armenia and Azerbaijan should maintain the Olympic truce regime, the U.S. co-chair of the OSCE Minsk Group, James Warlick said.
"The governments of Armenia and Azerbaijan should maintain the Olympic truce regime and stick to the ceasefire. Too many dead, don't you agree? " Warlick wrote on his official Twitter account on Feb.28.
Earlier, the presidents of Armenia and Azerbaijan re-committed to respecting the ceasefire on the contact line of Armenian and Azerbaijani troops during the Olympic Games in Sochi.
Nevertheless, despite the Olympic truce, the contact line between the Azerbaijani and Armenian armies remains tense.
The Armenian armed units violated the ceasefire at 15:30 on Feb.26 and fired on the positions of Azerbaijani Armed Forces. As a result, a junior sergeant of the Azerbaijani Armed Forces Kerem Nohbalaev died, the Azerbaijani Defense Ministry earlier said.
The conflict between the two South Caucasus countries began in 1988 when Armenia made territorial claims against Azerbaijan. Armenian armed forces have occupied 20 per cent of Azerbaijan since 1992, including the Nagorno-Karabakh region and seven surrounding districts.
Azerbaijan and Armenia signed a ceasefire agreement in 1994. The co-chairs of the OSCE Minsk Group, Russia, France and the U.S. are currently holding peace negotiations.
Armenia has not yet implemented the U.N. Security Council's four resolutions on the liberation of the Nagorno-Karabakh and the surrounding regions.
