FREETOWN, Muharram 25, 1437, Nov 7, 2015, SPA -- Residents of Sierra Leone's capital held a candlelit vigil and celebrations overnight to mark the end of an Ebola epidemic that has killed almost 4,000 people including more than 200 health workers since it began last year, Reuters reported. Following 42 days with no new cases, the West African nation's epidemic will be declared officially over on Saturday at a ceremony attended by President Ernest Bai Koroma and U.N. World Health Organization (WHO) representative Anders Nordstrom. Thousands of people gathered under the Cotton Tree, a massive tree in the centre of the capital, Freetown, overnight for a candlelight vigil organised by women's groups to pay tribute to health workers who died. --SPA 13:47 LOCAL TIME 10:47 GMT www.spa.gov.sa/w
