At least 98 people have been killed and more than 600 others are injured after multiple explosions at a military camp in Equatorial Guinea.

The state television channel TVGE broadcast footage of wrecked and burning buildings, with people - including children - being pulled from the rubble and the wounded lying on a hospital floor.

It showed images of a thick column of black smoke, which TVGE said was coming from the Nkoa Ntoma military camp in the economic capital Bata.

The first blast occurred in the early afternoon and in the early evening TVGE referred to “casualties” but said it had not determined whether there were any fatalities.

It is not yet known what caused the blasts, but early reports suggested they might have come from the camp"s armory, according to a journalist with the TV channel.
