Global efforts to stop Myanmar's civil war were "clearly not working", a UN expert warned Thursday as he urged leaders to starve the ruling junta of "money, weapons and legitimacy".
Describing a situation that has "gone from bad, to worse, to horrific", UN special rapporteur Tom Andrews said more than three million people have been displaced by fighting in the Southeast Asian nation in as many years.
The conflict is on the table at this week's meeting in Laos of Southeast Asian leaders, who pressed Myanmar's junta and its opponents to take "concrete action" to stop the bloodshed.
Since Mynamar's military seized power in February 2021, the junta has arrested more than 20,000 people in its crackdown on dissent and bombed opposition controlled areas, according to Andrews, a former member of the US Congress.
Yet despite its firepower, it has struggled to quash multiple armed offensives from ethnic groups and civilian militias across several states.
It has lost control of swathes of the country and garnered widespread international condemnation.
During a visit to Australia, Andrews said the regime had lost "tens of thousands" of soldiers in battle and had turned to conscription to reconstitute its forces.
"The junta has been responding to its losses by escalating attacks on civilian targets," he said, estimating junta forces have killed more than 5,600 civilians.
Andrews urged regional and global powers to deploy further legal, financial and trade sanctions.
"There is a great imperative for international action," he said, urging regional powers to starve the regime of "money, weapons and legitimacy".
"The international response to this crisis is clearly not working," he said while calling for an emergency summit.
"I'm worried that the deepening crisis in Myanmar has become invisible to much of the world," he said.
Andrews urged Australia and like-minded nations to help prosecute Myanmar's leaders for genocide and to back moves to bring war crimes charges before the International Criminal Court in the Hague.
Those prosecutions relate, for the most part, to decades of persecution of the Rohingya Muslim minority, who have been killed, abducted and forced over the border into neighbouring Bangladesh.
Bangladesh is home to around one million Rohingya refugees, most of whom fled a 2017 crackdown.
