Meanwhile the German embassy in the Sudanese capital has been partially set in fire and the German flag topping the building has torn down and replaced by an Islamic banner.
Staff members were all safe according to the German foreign ministry.
Just 400 metres away the British Embassy was also attacked.
"We can confirm that a demonstration is taking place in front of the embassy and that local police are at the scene," a Foreign Office spokesman said of the situation in Sudan.
