Ebola outbreak: USAID pledges additional $75m

The US Agency for International Development (USAID) announced today that it is making up to $75 million in additional funding available to fight Ebola - bringing the total up to $100 million so far.

It comes during a deadly outbreak in West Africa which has already killed more than 1,900 people.

USAID administrator Rajiv Shah told the BBC's Katty Kay that the agency will work with the World Health Organization (WHO) and other international groups to step up the global response to the crisis.
