Update for Thursday, January 21, 2016

Taliban suicide attack on a bus carrying employees of a TV production company associated with Tolo kills 7. As you may recall, the Taliban had threatened Tolo over its coverage of their occupation of Kunduz. As of 12:37 ET, Tolo's web sites appear to be down -- which may just be a coincidence. I'll keep trying. Tolo is back up.

Denunciation of the attack is widespread.

Pakistan claims attack on Bacha Khan university that killed 20 was directed from Afghanistan where Pakistani Taliban have taken refuge, but Afghan officials deny it.

U.S. forces are authorized to target IS in Nangarhar. If you thought they didn't already have such authority, the explanation is that U.S. forces are only authorized to attack Taliban in defense of themselves or Afghan forces. "IS" in Afghanistan is really a breakaway Taliban faction. This gives U.S. forces the authority to attack them because of their affiliation, even if there is no imminent threat.
