Rights organisation Save The Children has said that at least 43 children have been killed by armed forces in Myanmar since February's military coup.
The group said the country was in a "nightmare situation", with the youngest known victim just six years old.
Local groups have puts the overall death toll at 536 since the protests break out against the military takeover.
The UN's envoy to Myanmar has warned of the risk of an "imminent bloodbath" as the crackdown against pro-democracy protests in the country intensifies.
