The government of Burma failed to do enough to stop the spread of violence in March, the UN special envoy on human rights said on Tuesday. Tomas Ojea Quintana said he had serious concerns about renewed violence between Buddhists and Muslims in Burma. Human Rights Watch said recently at least 40 people died in the latest violence. “The warning signs have been there since the communal violence in Rakhine state last June and the government has simply not done enough to address the spread of discrimination and prejudice against Muslim communities across the country,” Quintana said in a statement.
