Liberia has closed all schools and quarantined several communities as it attempts to stop the spread of the deadly ebola virus.
All non-essential government workers were also put on 30 days compulsory leave as the country announced its anti-ebola action plan.
Security forces across the country have been ordered to enforce the new rulings.
Liberia had recorded 129 of the 672 deaths blamed on ebola as of July 23, according to the World Health Organisation.
Lewis Brown, Liberia's information minister, said: "This is a major public health emergency. It is fierce, deadly and many of our countrymen are dying and we need to act to stop the spread.

"This is a humanitarian crisis in Liberia. People are being given care at their homes until we can move them to the new unit."
