Many of the Islamist terrorists shot their way into the In Amenas compound on Thursday using the AK104 model of Kalashnikov, which was typically used by Libyan rebels in the war against Muammar Gaddafi.
They brought F5 rockets that also surfaced in the Libyan war, said the security source.
The Islamists wore the same type of outfits that Qatar provided to Libyan National Transitional Council rebels by Qatar – yellow flak jackets with brown patches, known as “chocolate chip” camouflage. The garments are copies of ones worn by Americans in the Gulf war.
The terrorists also employed 60mm gun-mortars used by France and Libyan rebels.
