Liberia's president has declared a curfew and is imposing a quarantine of a major slum in the capital Monrovia as the death toll mounts from Ebola.
President Ellen Johnson Sirleaf announced late Tuesday that movements now would be restricted between 9 p.m. and 6 a.m.
The country is already under a state of emergency, and the latest action also will block all movement in and out of West Point, home to at least 50,000 people.
Over the weekend, residents angered over the placement of an Ebola center in West Point looted the facility and 37 patients left who were supposed to be under surveillance. Health officials said that all of those later returned.
At least 466 people have died from Ebola in Liberia, and panic already has led to social unrest.
