The United States’ policy coordinator for the Indo-Pacific region said on Tuesday the situation inside military-ruled Myanmar was deeply concerning and continuing to get worse and the United States was looking at all possible scenarios there, according to a Reuters report.

"It's undeniable that the violence is spiraling," Kurt Campbell told an online event hosted by the Center for a New American Security think-tank.

Campbell said Washington, which has imposed sanctions on the coup leaders and their economic interests, had supported efforts of the Association of Southeast Asian Nations and others to try to begin a process of moving Myanmar back to democracy and was urging countries isolate the generals diplomatically.
