Bangladesh is accusing Myanmar's government of failing to tackle the concerns of over one million Rohingya Muslims who fled the country and is urging the UN Security Council to take action to ensure their safe return home.

Bangladeshi Ambassador Masud Bin Momen said in a letter to the council circulated today that while his government continues to engage with Myanmar "in good faith" on arrangements to return the Rohingya, "we regret that the necessary conditions for safe and sustainable return do not exist."
