A Taliban group in northwestern Pakistan has claimed responsibility for the killing of more than 20 people, including students and professors, at the Bacha Khan University, 25 miles from Peshawar.
A different faction of the Taliban has responded by saying they were "disowning" the Taliban group behind the deadly attack, calling the shootings "un-Islamic."
The region has been the target of a Taliban insurgency marked by killings and suicide bombings in recent years, though until this week, Pakistan's army had been credited with a successful crack-down on local violence.
