BENGHAZI (AFP) - A Moamer Gaddafi-era security official has been killed in Libya’s second city Benghazi, local officials said Saturday, in the latest attack highlighting a lack of security in the east of the country. “Lieutenant-Colonel Nasser al-Magrabi was found dead on his farm last night,” an official in Benghazi’s criminal investigations department told AFP on condition of anonymity. “He was shot,” the official said. Another official said the corpse was found “in a farm in the Sidi Faraj area” and that “investigations are now underway”. Both sources said Magrabi had worked for the former regime’s reviled internal security services in Benghazi during the era of slain dictator Gaddafi, who was unseated by an uprising in 2011. The killing comes a day after the head of Benghazi’s criminal investigations department, Abdelsalam al-Mahdawi, was kidnapped at gunpoint. His whereabouts remain unknown.
