Student groups took to the streets of the Pakistani city of Karachi to condemn the attack at the Bacha Khan University in Charsadda in the north west of the country.
As many as 30 people were killed when four gunmen scaled a wall under thick mist and proceeded to open fire.

One of the protesters questioned the level of protection at the university and the intelligence capabilities of the state: “The security forces know that universities are a target, why did they not provide adequate security? For how long will we in Pakistan be targeted and killed by the Taliban? For how long?’‘
An off-shoot of the Taliban, Hakimullah Mehsud, claimed responsibilty for the killings.
Tehreek-e-Taliban Pakistani, the main Taliban organisation in Pakistan, described the attack as un-Islamic.
The four gunmen were also killed in the bloodbath.
In 2014 130 students were killed at a school in the city of Peshawar, 50km from Charsadda.
