Liberia admits 17 Ebola patients have gone missing
Seventeen suspected Ebola patients have gone missing in Liberia after a health centre in the capital was attacked.
The Liberian government had previously denied they were missing, saying all patients had been moved to another facility.
The Ebola outbreak, which has spread from Guinea to Liberia, Sierra Leone and Nigeria, has killed at least 1,145 persons.
The World Health Organization has called for exit screenings of all travellers from affected countries.
It wants checks at airports, sea ports and major land crossings.
Already, several airlines have stopped flying to Guinea, Liberia and Sierra Leone.
