Britain on Monday announced sanctions on businesses linked to the warring parties in Sudan which has brought about a major humanitarian disaster in the country.
The British foreign office said the strict measures will include an asset freeze on companies linked to the Sudanese Armed Forces and its rival, the paramilitary Rapid Support Forces.
Targets of the sanctions include Alkhaleej Bank, a financial institution that has been financing the RSF, and Al-Fakher Advanced Works, a holding company used by the organisation to export gold proceeds of which are used to purchase weapons.
Fighting, which broke out between rival generals in the North African country on April 15 last year, has killed thousands and caused an estimated 1.8 million people to flee to neighbouring countries.
Aid workers say the conflict has led to a catastrophe in the country of 48 million, with many civilians enduring starvation, sexual violence, large-scale ethnic killing, and executions.
Red Rock Mining, a mining and exploration company that provides funds to the SAF, will also be sanctioned.
The Foreign Office said the company is closely linked to Defence Industries System, the economic and manufacturing arm of the SAF.
France, which is hosting an international conference on Sudan is soliciting for aid and increased attention on what officials say is a crisis crowded out by the ongoing conflicts in Ukraine and Gaza.
