MOSCOW, October 10 (RIA Novosti) - Armenian President Serzh Sargsyan will pay a brief visit to Moscow on October 12 on an invitation from his Russian counterpart Dmitry Medvedev, the Kremlin said Saturday.

Medvedev and Sargsyan met Friday during a summit of the post-Soviet Commonwealth of Independent States in the capital of Moldova, with Azerbaijani President Ilham Aliyev also taking part in the meeting chiefly dedicated to discussions of the Nagorny Karabakh issue.

Nagorny Karabakh, a region in Azerbaijan with a largely Armenian population, has been a source of conflict between the former Soviet republics since the late 1980s. The province has its own government and is de facto independent.
