Azerbaijan accuses Armenia of shooting dead five of its soldiers on the border of those two countries, a day after three Armenians were killed.
Armenia reports that three of its soldiers were killed in clashes with Azerbaijani forces in the disputed Nagorno-Karabakh region.

Anti-government protesters block streets in the Armenian capital Yerevan, continuing calls for Prime Minister Nikol Pashinyan to resign over the Nagorno-Karabakh ceasefire agreement with Azerbaijan. Riot police detain more than 40 protesters.
