In April 2014, an anti-terrorist training base called "Camp 27", located between Tripoli and the Tunisian border, was taken over by forces fighting under the control of Abd al-Muhsin Al-Libi, also known as Ibrahim Tantoush,[137] a long-serving Al-Qaeda organizer and former member of the Libyan Islamic Fighting Group.[138] The Islamist forces at Camp 27 have subsequently been described as part of the Libya Shield Force.[139] The Libya Shield Force was already identified by some observers as linked to al-Qaeda as early as 2012.[140][141]
