Sudan conflict: Landmark skyscraper in Khartoum engulfed in flames

Buildings caught fire in Khartoum after heavy fighting between army and rival forces.

The 18 -storey oil firm skyscraper is one of the most recognisable landmarks in the city.

It is not yet clear what caused the building's cone-like structure to catch fire.

The violence in Sudan began on 15 April , triggered by a power struggle between the army and the paramilitary Rapid Support Forces.
