Two women, who are mothers of victims of the Abu Salim prison massacre during the rule of Muammar Gaddafi, hold pictures of their sons during a demonstration in front of the prison in Tripoli April 5, 2013. Demonstrators demanded justice and a speedy trial for Abdullah al-Senussi, who was Gaddafi's spy chief. Senussi is suspected of playing a central role in the killing of more than 1,200 inmates at the Abu Salim prison in 1996. REUTERS/Ismail Zitouny (LIBYA - Tags: POLITICS CIVIL UNREST CRIME LAW)
