A group of 11 chief executive officers of international mining companies working in West Africa are calling for fewer travel restrictions in the face of the Ebola epidemic.

"We are understandably concerned about the impact of the Ebola virus on affected countries' economies and the well-being of their people, which is being compounded by subsequent decisions and actions that affect travel to and trade with the region," a joint statement said.

The letter was signed by ArcelorMittal's Lakshmi Mittal, London Mining's Graeme Hossie, Newmont Mining's Gary Goldberg and Randgold's Mark Bristow, among others.

The letter lists two demands. One is to end to travel bans, which have been instituted by African flight hubs South Africa and Kenya to lock out visitors from Sierra Leone, Liberia and Guinea, the hardest-hit countries. The second was for more international coordination on the crisis.
