The US government has issued sanctions against four Sudanese companies and several individuals for fuelling the war between rival military forces.
It said the sanctions would cut off key financial flows to the army and the Rapid Support Forces (RSF) - who get a lot of their funding from the country’s gold mines.
Seven weeks of conflict have forced close to 1.5 million people from their homes.
On Wednesday at least 18 civilians were killed during fighting between the rival military forces at a market in southern Khartoum.
