Britain has requested a new United Nations Security Council meeting on Myanmar for Friday, diplomatic sources told AFP on Tuesday.

The meeting would be behind closed doors at 1500 GMT, according to London's proposal, the same sources said.

The Security Council subsequently voiced "deep concern" over the change in governance, and called in a draft statement for the "release of all detainees" including Suu Kyi.

On Monday, China's diplomatic mission to the UN, traditionally reluctant for the Security Council to discuss Myanmar told AFP that there was a "general agreement among Council members... that there will be a meeting on Myanmar soon."

Myanmar security forces allegedly used live rounds and tear gas on protesters on Tuesday, leaving at least three people critically injured.
