US counter-insurgency advisor says IS becoming urban guerrilla threat

David Kilcullen, an Australian army veteran, became the senior counter-insurgency advisor to US General David Petraeus during the Iraq War and is considered a key architect of the "Awakening" strategy that helped turn the conflict around. In an exclusive interview, he told AFP the Paris attacks showed the Islamic State group (IS) was morphing from a terrorist threat into a "structured organisation" like the IRA in Ireland or ETA in Spain during the 20th century.
