Myanmar security forces opened fire on anti-coup protesters in the commercial capital Yangon on Sunday (March 14).
Protesters stood their ground behind shields and barricades as security forces lobbed tear gas canisters.
At least three people were killed, witnesses and domestic media said.
Video taken at the site showed protesters holding handmade shields and wearing helmets as they confronted security forces.
At least two people were killed elsewhere in the Southeast Asian nation, a day after the acting leader of the parallel civilian government said it will seek to give people the legal right to defend themselves.
More than 80 people had been killed as of Saturday in widespread protests against the military's seizure of power last month.
That's according to the Assistance Association for Political Prisoners advocacy group.
More than 2,100 people have been arrested, it said.
