The UN special envoy for Myanmar has warned that the country faces the possibility of civil war "at an unprecedented scale" and urged the UN Security Council to consider "potentially significant action" to reverse the February 1 military coup and restore democracy. Christine Schraner Burgener didn't specify what action she considered significant, but she painted a dire picture of the military crackdown in her virtual briefing to the council obtained by The Associated Press in which she also warned that the country "is on the verge of spiralling into a failed state". "This could happen under our watch," she said on Wednesday, "and failure to prevent further escalation of atrocities will cost the world so much more in the longer term than investing now in prevention, especially by Myanmar's neighbours and the wider region".
