Burma’s government-in-exile says the death toll from Cyclone Mocha has topped 400, with many more missing and unaccounted for. The storm made landfall Sunday with the strength of a Category 5 hurricane — one of the most powerful cyclones to hit the region. Burma’s National Unity Government on Wednesday accused the ruling military junta of blocking aid agencies from accessing the hard-hit Rakhine state, following reports that soldiers attacked Rohingya Muslims just before the storm’s arrival.
