In the central city of Monywa, which has turned out huge crowds to protest the military takeover, three people were shot, including one in the head, reported the Democratic Voice of Burma, an independent television and online news service. Reports on social media said two people there were killed.
In Myingyan in the same central region, multiple social media posts reported the shooting death of a 14-year-old boy. A second shooting death was reported later.
Two other deaths were reported elsewhere.
Demonstrators have regularly flooded the streets of cities across the country since the military seized power on Feb. 1 and ousted the elected government of leader Aung San Suu Kyi. Their numbers have remained high even as security forces have repeatedly fired tear gas, rubber bullets and live rounds to disperse the crowds, and arrested protesters en masse.
