From Basim: "When I first heard about the "little known Khorasan group" - and only within the last few days of course - I immediately knew it was another way of saying "Nusra Front" but Western capitals were reluctant to do so as Nusra has strangely come to symbolize moderation among the radicals. So here you go:
"Somsam Islam, a member of the better-known Al Qaeda-linked rebel group in Syria, Al Nusra Front, said Al Qaeda leaders in Pakistan and Afghanistan sent “a group of brothers” to be leaders within Al Nusra. They came to be known among other fighters by the moniker Khorasan, Islam said in a Skype chat." "
