Protests have hit the Liberian capital Monrovia, after a quarantine was imposed to halt the spread of Ebola.
Police opened fire on the protestors, leaving four people injured. Liberia is the worst affected country in the current crisis, with at least 576 deaths.
The protestors said the quarantine, enforced with a heavy police presence and barbed wire, stopped them from obtaining food and working.
A total of 1,350 have died in four countries, Liberia, Guinea, Nigeria and Sierra Leone.
South Africa meanwhile has banned the arrival of non-citizens from West African countries affected by the deadly virus. Senegal has suspended flights with the countries and closed its border with Guinea.
The African Union has announced it will send a special team to the West African countries, including volunteer doctors, nurses and other medical personnel.
