Peshawar school attack: Malala Yousafzai 'heartbroken'

Pakistani child education activist and Nobel Prize winner Malala Yousafzai says she is ''heartbroken'' by the news of a Taliban massacre at a school in Peshawar, killing 141 people, 132 of them children.

The attack - the Taliban's deadliest in Pakistan - has been widely condemned.

Malala Yousafzai, 17, was shot in the head by Taliban gunmen in October 2012 for campaigning for girls' education.
