The World Health Organization has declared the latest Ebola outbreak an international emergency, as cases continue to rise in the Democratic Republic of Congo and neighbouring Uganda - including infections reported in the capital, Kampala.

Some 88 people have died from the highly contagious haemorrhagic fever in the DR Congo, with one death in Uganda, and at least 336 suspected cases.

At least 80 people have died in what the World Health Organization says potentially could be a "much larger outbreak than what is currently being detected and reported".
