Sudan grapples with economic crisis

Sudan's president says unless weeks of border fighting with South Sudan is resolved there will be no talks on oil or trade.

Tension has been high since South Sudan gained independence from Sudan last July.

South Sudan inherited the majority of the region's oil fields in the split.

Sudan's oil revenue has fallen this year by $2.2bn.

As Mohamed Vall explains, it's one of the reasons why Khartoum is facing an economic crisis.
