Myanmar security forces opened fire on pro-democracy protests on Saturday killing five people, a protester and media said, as the military reinforced its bid to end dissent with arrest warrants for online critics and internet blocks.

Despite the killing of more than 550 people by the security forces since the Feb. 1 coup, protesters are coming out every day, often in smaller groups in smaller towns, to voice opposition to the reimposition of military rule.

Security forces in the central town of Monywa fired on a crowd killing thee people, the Myanmar Now news service said, while one man was shot and killed in another central town, Bago, and one in Thaton to the south, the Bago Weekly Journal online news portal reported.
