KABUL MOSQUE EXPLOSION LEAVES MULTIPLE DEAD, DOZENS INJURED
GEN. PETRAEUS: The real concern actually is not actually al Qaeda. … The real concern, though, is the Islamic State. That is the organization that has carried out horrific attacks - two of them yesterday alone against a mosque and another gathering place, one in Kandahar, one in Kabul - that killed dozens and dozens of both Taliban officials and innocent civilians. They have been carrying out, again, truly barbaric attacks. And the concern really about international extremism coming from Afghanistan, I think is much more connected with the Islamic State now than it is about al Qaeda's senior leadership, though you clearly have to keep an eye on that. And that clearly was done.
