Following the massacre at a school in the Pakistani city of Peshawar which left 141 people dead, the Indian children's rights activist and Nobel laureate Kailash Satyarthi has called on the Taliban terror group to take him instead of children.

"I beg the Taliban, take me and leave these children," he told NDTV following the news that over 100 children were killed at the military school.

"It's the most shocking incident, in my knowledge, in my life. These children are my children" said Satyarthi.

At least 141 people, mostly children, were killed in the massacre and 122 injured after seven militants - dressed as security forces - entered the building shooting at students and detonating at least one suicide bomb.

The siege on the school ended when Pakistani authorities killed all of the attackers who participated in the assault which has been confirmed as the deadliest ever by the terror group in Pakistan.

Education activist and Nobel Peace Prize winner Malala Yousafzai joined Satyarthi in condemning the "atrocious and cowardly" attack on the Pakistan school.

"I am heartbroken by this senseless and cold-blooded act of terror in Peshawar that is unfolding before us" she said. "Innocent children in their school have no place in horror such as this.

"I condemn these atrocious and cowardly acts and stand united with the government and armed forces of Pakistan whose efforts so far to address this horrific event are commendable.

"I, along with millions of others around the world, mourn these children, my brothers and sisters - but we will never be defeated."

Pakistani Prime Minister Nawaz Sharif said that the attack was a "national tragedy" while Pakistani opposition leader and former cricket captain Imran Khan said it was "utter barbarism".
