Twenty-seven people were killed when an ammunition depot exploded in the main southern Sudanese city of Juba yesterday.
But local residents said the death toll must be considerably higher than the official figure.
When the ammunition dump exploded, artillery shells and mortars rained down up to two km away and the fireball at the centre destroyed many houses.
Dozens of houses made of grass as well as local government and police offices were destroyed.
Another 75 people were injured in the explosions and their aftermath.
As many as 1,600 people lost their homes.
