The number of people killed in the Ebola outbreak has risen above 4,000, the World Health Organization has said.
The latest figures show there have been 8,376 cases and 4,024 deaths in the worst-affected West African nations of Guinea, Liberia and Sierra Leone.
The news comes as Liberian MPs refused to grant the president additional powers to deal with the Ebola crisis.
President Ellen Johnson Sirleaf has already declared a state of emergency that allows her to impose quarantines.
