The death toll from the Ebola outbreak in West Africa is now at least 1,350 people, according to the World Health Organisation .

The latest figures show the deaths are mounting fastest in Liberia, which now accounts for at least 576 of those who have died from the disease.

The UN health agency also warned in its announcement that "countries are beginning to experience supply shortages, including fuel, food, and basic supplies".

This comes after a number of airlines and shipping services have halted transport to the worst affected capitals of Liberia, Sierra Leone and Guinea.

In a bid to halt the disease's spread, authorities in Liberia have quarantined a huge slum that is home to 50,000 people. Protests erupted in West Point, where residents threw rocks at police.
