The US supports peaceful resolution of the Armenia-Azerbaijan Nagorno-Karabakh conflict, said the US Ambassador to Azerbaijan Robert Cekuta June 21.

The diplomat highlighted the importance of a peaceful resolution on the conflict, the US embassy in Baku tweeted June 21.

The conflict between the two South Caucasus countries began in 1988 when Armenia made territorial claims against Azerbaijan. As a result of the ensuing war, in 1992 Armenian armed forces occupied 20 percent of Azerbaijan, including the Nagorno-Karabakh region and seven surrounding districts.

The 1994 ceasefire agreement was followed by peace negotiations. Armenia has not yet implemented four UN Security Council resolutions on withdrawal of its armed forces from the Nagorno-Karabakh and the surrounding districts.
