Sierra Leone Ebola lockdown will work, says minister.

Sierra Leone - one of the countries worst hit by West Africa's Ebola outbreak - has announced a three-day lockdown to try to tackle the disease.

From 19 to 21 September people will not be allowed to leave their homes.

The medical charity Medecins Sans Frontieres (MSF) says the lockdown will not work, forcing infected people underground.

However, Sierra Leone's justice minister, Frank Kargbo, says it puts the country in a better position to fight the spread of the disease.
