Across Myanmar, opponents of the ruling junta on Sunday mourned the killings of at least 114 people by security forces in the bloodiest day since the military coup on Feb. 1, but vowed to keep protesting to end army rule.

Children were among those killed on Saturday, Myanmar's Armed Forces Day, according to news reports and witnesses, in a crackdown that drew renewed criticism from Western countries and was denounced by the U.S. envoy as "horrifying."

"We salute our heroes who sacrificed lives during this revolution and We Must Win This REVOLUTION," one of the main protest groups, the General Strike Committee of Nationalities (GSCN), posted on Facebook.
