RANGON: Myanmar security forces opened fire on Sunday, witnesses said, at people gathered for the funeral of one of the 114 people killed the previous day, the bloodiest day of protests since the military coup on Feb. 1.

There were no immediate reports of casualties in the firing on the funeral in the town of Bago, near the commercial capital Yangon, according to three people who spoke to Reuters.

"While we are singing the revolution song for him, security forces just arrived and shot at us," said a woman called Aye, who was at the service for Thae Maung Maung, a 20-year-old student who was shot on Saturday. "People, including us, run away as they opened fire."

Three people were killed in firing on Sunday in separate incidents elsewhere, witnesses and news reports said. One person was killed when troops opened fire overnight on a group of protesters near the capital Naypyitaw, Myanmar Now news reported.

So far on Sunday there were no reports of large-scale protests in Yangon or in the country's second city, Mandalay, which bore the brunt of the casualties on Saturday, Myanmar's Armed Forces Day. Funerals were held in many places.
