Police officers detain opposition supporters blocking the Armenian Foreign Ministry building during anti-government demonstrations in the capital Yerevan on May 24, 2022. - Yerevan has been gripped by anti-government protests since mid-April, with opposition parties demanding Prime Minister Nikol Pashinyan's resignation over his handling of a territorial dispute with Azerbaijan. Arch-foes Armenia and Azerbaijan fought two wars -- in 2020 and in the 1990s -- over the long-contested region of Nagorno-Karabakh. Six-weeks of fighting in autumn 2020 claimed more than 6,500 lives and ended with a Russian-brokered ceasefire agreement. Under the deal, Armenia ceded swathes of territory it had controlled for decades, and Russia deployed some 2,000 peacekeepers to oversee the truce. (Photo by Karen MINASYAN / AFP)
