William Pooley's plea for action on Ebola

A leading charity has warned that a rate of five new Ebola cases an hour in Sierra Leone means healthcare demands are far outstripping supply.

Save the Children said there were 765 new cases of Ebola reported in the West African state last week, while there are only 327 beds in the country.

Experts and politicians are meeting in London to debate a global response to the crisis.

Speaking at the event, British nurse William Pooley, who contracted Ebola in Sierra Leone but recovered, called for action to stop the "horror and the misery" that he witnessed.
