UK International Development Secretary Rory Stewart has called for the response to the Ebola outbreak in the east of the Democratic Republic of Congo to be stepped up considerably and fast.
Describing the outbreak as potentially devastating for the region, he said more money was needed as well as British expert staff on the ground, where more than 1,200 have died since August.
Describing the stakes as very high, Mr Stewart said other international donors also needed to contribute more.
Meanwhile, the head of the World Health Organization, Tedros Adhanom Ghebreyesus, has urged rival Congolese political factions to unite in the fight against Ebola.
Efforts to stop the virus spreading have been undermined by insecurity, attacks on health facilities and mistrust – with some people still not believing the virus is real.
