A study of a cluster of Ebola cases that appeared in Liberia last year, months after the country was declared Ebola-free, has found that the virus re-emerged after lying dormant in a female survivor. The results suggest Liberia and the other African countries at the centre of the outbreak should maintain high levels of vigilance for longer than thought to contain any future flare-ups of the deadly haemorrhagic fever. World Health Organization data show West Africa's Ebola epidemic killed more than 11,300 people and infected some 28,600 as it swept through Guinea, Sierra Leone and Liberia from 2013 in the world's worst outbreak of the disease.
A suicide bomber driving a car killed at least 17 people and wounded more than 40 others on Saturday in an attack near a group of Shi'ite Muslim pilgrims in a southeastern suburb of Baghdad, Iraqi police sources said. There was no immediate claim of responsibility for the blast at a market in the Nahrawan district but Islamic State militants regularly attack Shi'ite Muslims, whom they consider apostates. The pilgrims had been heading to Baghdad's Imam Kadhim shrine to commemorate the 8th century death of one of Shi'ite Islam's senior figures.
Hundreds of demonstrators jostled with police in riot gear outside a California hotel where Republican presidential frontrunner Donald Trump gave a speech, forcing the candidate to duck into a back entrance. At one point, several dozen protesters broke through barricades and attempted to storm the hotel where the California Republican Party Convention was taking place on Friday, but police, some wielding batons, were able to push them back. The demonstrators waved banners that read "No hate, no racism, no Trump," "We need a uniter, not a divider" and "Trump is the modern day Hitler." Several carried Mexican flags.
