Al Qaeda is exploiting the conflict in Libya to acquire weapons, including surface-to-air missiles, and smuggle them to a stronghold in northern Mali, a security official from neighbouring Algeria told Reuters on April 4, 2011. He also said he had information that al Qaeda’s north African wing, known as al Qaeda in the Islamic Maghreb (AQIM), had acquired from Libya Russian-made shoulder-fired Strela surface-to-air missiles known by the NATO designation SAM-7.
