Myanmar ? Myanmar’s isolationist regime has approved all pending visas for U.N. relief workers to enter the country, the United Nations said Thursday, nearly a month after a cyclone left more than 2 million people in need of aid.

Greater numbers of foreign aid staffers also were entering the Irrawaddy delta, a low-lying region which took the brunt of the May 2-3 cyclone, the U.N. said in a statement.

The storm left an estimated 2.4 million people in desperate need of food, shelter and medical care, according to the U.N. The government says the cyclone killed 78,000 people and left 56,000 missing.

Myanmar’s leaders are leery of foreign aid workers and international agencies, worrying they could weaken the junta’s grip on power. The generals also don’t want their people to see aid coming directly from countries like the U.S. that the junta has long treated as a hostile power.
