Russia expressed concern on Wednesday about plans for a U.S.-Armenian military exercise in Armenia next week, saying it would be watching closely.

The Armenian defence ministry said the purpose of the Sept. 11-20 "Eagle Partner 2023" exercise was to prepare its forces to take part in international peacekeeping missions.

Kremlin spokesman Dmitry Peskov told reporters the exercise required alertness on Russia's part, and Moscow would be monitoring it.
