Myanmar has agreed to allow aid to resume to the troubled north of Rakhine state and permit international observers to monitor whether help is reaching people displaced by violence, diplomats on a mission to the area told reporters on Thursday.

The diplomats, including the ambassadors of the United States and Britain and the top United Nations representative to the country, also called for an "independent and credible investigation" into attacks on security forces on Oct. 9 and the army operation launched in their aftermath.

The mission spent two days in northern Rakhine, closed to aid workers and observers for more than three weeks, and visited several villages, but were not taken to the scene of some of the most serious allegations of abuses by troops against civilians.
