Parents of Pakistani children killed in the 2014 attack on a Peshawar school gathered on December 16 to mark the second anniversary of the massacre.
The attack by Taliban militants on Peshawar’s Army Public School killed 150 people, mostly children.
Pakistan’s army chief, General Qamar Javed Bajwa, told parents gathered at the school on December 16 that the violence against innocent children was an attack "on humanity" and was one of the most painful and unforgettable moments in the country’s history.
In a statement, Prime Minister Nawaz Sharif expressed his sympathies to the victims' families, saying the entire country felt and shared the pain of the tragedy.
Sharif also said Pakistan has responded to the killings by intensifying action against militants.
Pakistan’s government and army say most of the Pakistani Taliban members linked to the killings have been captured or killed in the last two years.
