Amnesty International says rival militias and armed groups in Libya are committing "mounting war crimes" with impunity.

In a new report released Thursday, it accuses fighters of having complete disregard for civilian lives, saying militants have fired GRAD rockets and artillery into civilian neighborhoods. It also says "scores of civilians have been abducted by armed groups."

"In today's Libya the rule of the gun has taken hold. Armed groups and militias are running amok, launching indiscriminate attacks in civilian areas and committing widespread abuses, including war crimes, with complete impunity," Deputy Director for the Middle East and North Africa Hassiba Hadj Sahraoui said in a statement.

Libya is mired in its worst turmoil since 2011, with the country deeply fractured and having two rival governments.
