More than 300 children have died in the Ebola outbreak in the eastern Democratic Republic of the Congo (DRC), the UN said on Friday, as health experts urged trials of the only vaccine against the disease to halt further spread of the rare Bundibugyo species.

DR Congo Ebola outbreak has killed 1,707 of 3,802 confirmed cases since May. The Bundibugyo strain has no approved vaccine as WHO races to start trials.

DRC Ebola outbreak tops 4,053 cases and 1,850 deaths, severely affecting children and crippling vital health services in Ituri Province, UNICEF warns.
