PESHAWAR: Mubashir Subhan was in the school auditorium, surrounded by friends, when Tehreek-i-Taliban Pakistan (TTP) gunmen came crashing in. The first bullet grazed the back of his head, the second passed through his shoulder, and the third struck his left hand.
At least 144 lives were lost in Peshawar's Army Public School (APS) massacre of December 16, 2014, the deadliest attack in Pakistan's history.
One year on, those who survived now study in the same rooms where they huddled in terror as their classmates fell around them.
The majority of them were children, many of whom were in the auditorium with Subhan when nine attackers armed with guns and explosives went on a cold-blooded killing spree.
Many are still gripped by a sense of paralysis when they enter APS.
"I feel unable to function. I keep remembering everything," Subhan, a bearded, soft-spoken 16-year-old says.
One year on, those who survived now study in the same rooms where they huddled in terror as their classmates fell around them.
When he is alone, memories of the friends who died alongside him that day come crowding in, and he says he cannot fathom how quickly his life was shattered.
"I think about how I used to be with my friends," he says.
His parents also remember how he used to be, saying their confident, outgoing son was transformed by the hours-long siege.
"The slightest of things he takes as though a bullet hit him," says his father Subhan Uddin.
"When he comes home, he just locks himself in his room. He doesn't meet us or his brothers or sisters or friends. He just sits and thinks."
'They made our college a graveyard'
The auditorium is now a sports hall and soldiers stand atop recently fortified walls as children play on the green, expansive grounds below.
But the trauma has lingered, says Andaleeb Aftab, a chemistry teacher at the school who fled into a bathroom with other staff after gunmen opened fire on them in a hallway.
Aftab's son, 16-year-old Huzaifa, was among those who died in the auditorium.
In their last exchange, she said, he came to the staff room and asked her for pocket money.
"But I told him I just saw you taking pocket money from your father in the parking lot — so don't double cross me!" she remembers.
Aftab was trapped in the bathroom until evening, listening for hours as the attackers blew themselves up one by one. It was only after she was rescued that she learned her son had died.
"They made our college a graveyard," she says.
Mathematics teacher Abu Bakar, 43, now uses a cane to walk after he was shot three times when he threw himself in front of four students fleeing the gunmen. Three of them survived.
"I'm a teacher and I have to do my duty no matter what," he says.
'Unfit for duty'
For other survivors the destructive effects of December 16 continue to shape their future.
Waheed Anjum, 18, was shot three times during the attack — once in each arm and once in the chest.
Numerous operations meant he was out of school for six months, affecting his final grades, as well as his chances of either entering a college engineering programme or becoming a soldier like his father.
"I can't move my arms properly. I can't lift weights," he said.
"They have declared me unfit."
'We can't forget'
On Wednesday, the anniversary of the attack, Prime Minister Nawaz Sharif and Chief of Army Staff General Raheel Sharif will join Pakistan Tehreek-i-Insaf leader Imran Khan for a ceremony at the school marking the massacre.
The attack on APS saw a shift in public opinion on the country's more than decade long struggle against militancy.
Parents seeking vengeance backed by a shocked and outraged public drove support for a nationwide military-led crackdown.
The army intensified Operation Zarb-i-Azb in tribal areas where militants had previously operated with impunity, and the government launched the sweeping National Action Plan to tackle militancy.
The efforts have seen levels of militancy-linked violence fall to their lowest levels since 2007, the year the TTP came into being.
But critics have voiced concerns over a failure to tackle the long-term causes of the violence, suggesting the drop in attacks may be a veneer covering the extremism that still bubbles beneath society's surface.
On Sunday, just four days before the anniversary, a bomb blew apart a clothes market in Kurram Agency's Parachinar, killing some two dozen people.
"It's been a whole year but we can't forget a single moment of that day," chemistry teacher Aftab says.
"Many of the students are still facing psychiatric problems. Many of the students are still injured."
They are recovering "a little", she said, but the suffering goes on.
"We're not out of the 16th of December."
