Rebels in the Libyan capital, Tripoli, have arrested one of the most prominent guards loyal to slain leader Muammar Gaddafi. Jamila Durman, who was a member of Libya's Revolutionary Committees, allegedly supported and attended the executions of many Libyans. A security source who asked to remain anonymous said that Durman was hiding disguised in a house in the outskirts of Tripoli and was preparing to escape through the Ras Ajdir crossing to Tunisia. The same source said that there a number of  "Revolutionary Nuns”, like Durman, throughout Libya and that they are now investigating them and their whereabouts, as the group constituted a "threat to national security of the country and incited sedition". The “Revolutionary Nuns” were known to participate in executions across Libya in the 1980s. Sources state that Durman along with the Revolutionary Guards and Revolutionary Committees helped execute suicide attacks with the National Front for the Salvation of Libya (NFSL) in 1984, which the regime brutally suppressed, resulting in many deaths. Earlier, one of the Revolutionary Nuns, a Lebanese named Aziza Ibrahim and was part of Gaddafi's guard about 20 years ago, said that Jamila Durman was "a source of horror" even to the presidential security detail. Durman was reportedly the one who shot killed Colonel Hassan Ashkar, Gaddafi’s cousin, when he raised his voice at the latter during an argument.   The Revolutionary Nuns group was not limited to Libyans, and included women from several Arab and African countries.
