Armed men claiming that “there’s no Ebola” in Liberia raided a quarantine centre for the deadly disease in Monrovia overnight, prompting at least 20 patients infected with the deadly virus to flee, a witness said Sunday.“They broke down the door and looted the place. The patients have all gone,” said Rebecca Wesseh, who witnessed the attack and whose report was confirmed by residents and the head of Health Workers Association of Liberia, George Williams.
