Armed groups in western Libya attack activists

Human Rights Watch says that activists in western Libya have been physically attacked and threatened by armed groups, some affiliated with UN-backed government based in the country's capital, Tripoli. The statement by the New York-based watchdog on Thursday says that Libyan"authorities seem unable to rein in the attackers, enabling them to operate with impunity."It says many activists have fled the country after threats or attacks by armed groups and militias.
