Residents in the Malian capital Bamako say panic over suspected cases of Ebola has prompted public demonstrations.
Ibrahim Coullibaly, who lives in the Lassa neighborhood of Bamako, said several people were wounded Friday when police tried to disperse the protesters.
The crowds were angry over reports that several people suspected of having the deadly disease were being held in isolation in their neighborhood.
Health officials in Mali said Thursday they were investigating three suspected cases of Ebola amid an outbreak in two other West African countries.
Already at least 84 people have died in neighboring Guinea, while two deaths have been confirmed in Liberia amid the first Ebola outbreak in West Africa in two decades.
Ebola is one of the deadliest diseases on Earth, killing up to 90 percent of patients.
