Nobel-prize winner Malala Yousafzai has said she is "heartbroken by the attack on students and staff at the Bacha Khan University" which may have killed up to 40 people.
In a statement, Malala, who was shot by the Taliban for her views on female education, "strongly condemned" the attack.
I am heartbroken by the attack on students and staff at the Bacha Khan University in Charsadda and strongly condemn this brutal assault. My prayers are with the families of all the victims and all those who suffer as a result of extremist violence.
This brutality must be stopped. The authorities must act to ensure that all schools and universities are safe. I urge all people with peace in their hearts to renew their resolve to stand up to terrorism and ignorance and work together to protect life and learning.
This attack happened on the 28th anniversary of the death of Abdul Ghaffar Khan who was a great freedom fighter, a man of peace. I hope his message of non-violence and harmony will prevail and end intolerance in our society.
