Explosions, fire at arms factory in Sudan's capital KHARTOUM (Reuters) - A huge fire broke out after a loud explosion on Tuesday night at an arms factory in Sudan's capital Khartoum, a Reuters witness said. Soldiers blocked roads to the factory where more explosions took place as firefighters tried to contain the blaze, a Reuters reporter at the scene in southern Khartoum said. The state-linked Sudanese Media Centre said the fire and explosions had occurred at the Yarmouk ammunition factory. The army spokesman was not immediately available for comment.
