Monday marks exactly five years since Osama Bin Laden the man branded "the world's most wanted terrorist" was cornered and killed by US Navy Seals in Pakistan "Bin Laden's death did leave a legacy," says Dr Sajjan Gohel, of the Asia Pacific Foundation, "but to some extent, it has been usurped by Isis who have taken over and built on his goals for creating a transnational terrorist project" "IS has gone in different directions from Bin Laden's al-Qaeda," says Dr Gohel. "It also engages in criminal activity, human trafficking and is open to recruiting women, all of which al-Qaeda was opposed to."
