DHAKA: The World Health Organization has said the speed and extent of the Ebola outbreak in West Africa is "unprecedented".

The WHO's Dr Keiji Fukuda expressed concern over so-called "shadow zones", areas which cannot be reached and where patients are not being detected.

The organisation confirmed 142 new cases of the disease had been reported since 19 August, as well as 77 deaths.

Already more people have died in this outbreak of Ebola than in any other.

At least 1,427 people have now died in the outbreak so far, with the number of cases now standing at 2,615.
