(VOVworld) - Seventeen Ebola patients in Liberia who fled a quarantine centre in Monrovia after it was attacked by club-wielding youths were still missing on Sunday, a blow to efforts to contain the deadly virus. The attackers, mostly young men armed with clubs, shouted insults to President Ellen Johnson Sirleaf and yelled "there's no Ebola," prompting patients to flee the center. Meanwhile, the bodies of 12 dead patients were removed by their relatives. Security in Liberia is weakening. Suspected Ebola patients tried to break into the UN peace keeping force’s headquarters. The Ebola epidemic has killed 1,145 people. 2,127 people have been infected with the virus, prompting the WHO declare an emergency around the globe.
