Bangladesh has told three international aid agencies not to help thousands of Muslim Rohingya refugees who have been fleeing into Bangladesh to escape violence in neighbouring Myanmar.

Some 100,000 people, both Bangladeshis and Rohingya refugees, depend on the services of France's Médecins Sans Frontières, British-based Muslim Aid and Action Against Hunger.

Aid agencies fear that conditions in refugee camps in Bangladesh are about to deteriorate even further as a result of the ban.
