The 60 pupils Waqar Ullah Khattak was supervising had barely started working through their test papers when the sound of gunfire began echoing around the chilly examination hall at the army public school in Peshawar. 
 
 In the terror-wracked capital of one of Pakistan’s most violent provinces, Khattak and his fellow invigilators immediately recognised the sound of AK-47 assault rifles. “We had received some training on how to deal with unexpected attacks,” he said. “I told the students to hide on the floor.” 
 
 It was to be the deadliest terrorist attack in Pakistan in memory. By the early evening, 141 people had been killed – 132 children and nine staff. The army’s spokesman said that 125 people had been injured, including seven army rescuers. 
 
 The attack started before 10am, when seven terrorists wearing suicide bomb vests under their clothes crossed over the undefended back wall at the school in the upmarket military Cantonment area. One official said the men had parked a lorry next to the school and simply hopped across from the roof of the vehicle. Workers in the school’s kitchen said they initially mistook the heavily armed group for pupils late for classes, attempting to slip in unobserved.

 Once inside, the men began a pitiless killing spree, going from classroom to classroom in the male-only section of the academy, which educates 1,000 boys aged five to 18, many of them the sons of army officers. 
 
 “As soon as we entered the hall, firing started behind us in the hall. Our teacher said close the doors,” one pupil was quoted as telling NDTV. “We closed the doors and suddenly they entered, breaking the doors … As soon as we hid under tables, they fired bullets at our legs and our heads and then they burned our madam. They burned our madam. The firing continued but we didn’t move because whoever moved got shot at.” 
 
 A spokesman for the Tehreek-e-Taliban Pakistan (TTP), as the country’s main Taliban franchise calls itself, claimed the attackers were under orders to kill only boys beyond the age of puberty. But Akbar Khan, the father of a 17-year-old student, Omar, said they shot indiscriminately. “As a school prefect he was with a group being trained in first aid by the army when the terrorists burst in,” Khan said of his son. He said the firing triggered a stampede. “He [Omar] was hit in the elbow but managed to rush from the area and was among the first children to be brought to the hospital.” 
 
 Although teachers did their best to protect their students, locking doors and barricading windows, the death toll rose throughout the day as elite Special Services Group commandos attempted to gain control of the site. 
 
 In the mid-afternoon, two loud blasts echoed across the city – most likely the sound of bomb vests being detonated by men who, according to some witnesses, spoke to each other in Arabic.

 Groups of pupils still wearing their smart green blazers were rescued by soldiers or managed to escape and were ferried to hospital. Anxious parents tried to break through the army cordon. Some said security at the school had been insufficient given the level of threat. 
 
 “Every second house we have a dead body and the entire city is in gloom,” said Akbar Khan, arguing that while the front of the school had an army guard, the back wall should have been guarded too. “Some people are cursing the [local] government, some people the national government, and some are blaming the army chief.” 
 
 Later the Pakistani government launched what it called “massive air strikes” in the Khyber region against Taliban outposts. 
 
 At Peshawar’s two hospitals, people flocked to try to donate blood after stocks ran low, and parents searched desperately for their children. “My son was in uniform in the morning. He is in a casket now,” one man, Tahir Ali, told Associated Press as he came to collect the body of 14-year-old Abdullah. “My son was my dream. My dream has been killed.” 
 
 Irshadah Bibi, whose 12-year-old son was among the dead, beat her face in grief and threw herself against an ambulance, Agence France–Presse reported. “Oh God, why did you snatch away my son?” she wept. “What is the sin of my child and all these children?”

 Khattak, the exam invigilator, said a scene of carnage awaited him when, midway through the fighting, rescuers reached him and his pupils and escorted them to safety. “As we were running out we saw blood and dead students lying around on the floor – I will never forget it,” he said. 
 
 A student who survived the attack said soldiers came to rescue students during a lull in the firing. “When we were coming out of the class we saw dead bodies of our friends lying in the corridors. They were bleeding. Some were shot three times, some four times.” 
 
 Shahrukh Khan, a 15-year-old student at the school who was shot in both legs, said he witnessed the murder of one member of staff. “One of my teachers was crying, she was shot in the hand and she was crying in pain,” Khan told Reuters, lying on a bed in the city’s Lady Reading hospital. “One terrorist then walked up to her and started shooting her until she stopped making any sound. All around me my friends were lying injured and dead.” 
 
 The teenager said he had decided to play dead after being shot, stuffing his tie into his mouth to prevent himself from screaming. “The man with big boots kept on looking for students and pumping bullets into their bodies. I lay as still as I could and closed my eyes, waiting to get shot again,” he told Agence France-Presse. 
 
 “My body was shivering. I saw death so close and I will never forget the black boots approaching me – I felt as though it was death that was approaching me.” ||||| Story highlights Children "are dying on the frontline in the war against terror," Pakistan's defense minister says 
 
 The death toll has climbed to 145 people, included 132 children and the school's principal 
 
 Attackers gunned down students taking an exam in an auditorium, military spokesman says 
 
 Attack was on a school mostly for soldiers' children; many of the dead between 12 and 16 
 
 "'God is great,'" the Taliban militants shouted as they roared through the hallways of a school in Peshawar, Pakistan. 
 
 Then, 14-year-old student Ahmed Faraz recalled, one of them took a harsher tone. 
 
 " 'A lot of the children are under the benches,' " a Pakistani Taliban said, according to Ahmed. " 'Kill them.' " 
 
 By the time the hours-long siege at Army Public School and Degree College ended early Tuesday evening, at least 145 people -- 132 children, 10 school staff members and three soldiers -- were dead, military spokesman Gen. Asim Bajwa said. More than 100 were injured, many with gunshot wounds, according to Khyber Pakhtunkhwa province Information Minister Mushtaq Ghani. 
 
 The death toll does not include the terrorists who attacked the school, bursting into an auditorium where a large number of students were taking an exam and gunning down many of them within minutes, Bajwa said.

 "They started shooting indiscriminately," Bajwa said, "and that's where maximum damage was caused." 
 
 Pakistani Taliban spokesman Mohammed Khurrassani said the militants scaled the school's walls around 10 a.m. (midnight ET), intent on killing older students there. 
 
 The Taliban had "300 to 400 people ... under their custody" at one point, said Khurrassani, whose group is called Tehreek e Taliban Pakistan, or TTP. But Bajwa said there was no hostage situation, as the attackers' focus was shooting to kill rather than taking captives. 
 
 They were eventually met by Pakistani troops who pushed through the complex building by building, room by room. By 4 p.m., they'd confined the attackers to four buildings. A few hours later, all the militants -- seven of them, according to Bajwa -- were dead. 
 
 Pakistani authorities spent Tuesday night inside the school in Peshawar, a city about 120 kilometers (75 miles) from the country's capital, Islamabad, looking for survivors, victims and improvised explosive devices planted to worsen the carnage.

 As they searched, they discovered that the school's principal was among the terrorists' victims. 
 
 The attack drew sharp condemnation from top Pakistani officials, who vowed that the country wouldn't stop its war against the Taliban. 
 
 "We are undeterred. ... We will not back off," Defense Minister Khawaja Asif told CNN. 
 
 But he said the ambush at the school is another example of how great his nation's sacrifices have been in fighting that's raged for more than a decade. 
 
 "Even the children are dying on the frontline in the war against terror," he said. "The smaller the coffin, the heavier it is to carry. ... It's a very, very tragic day." 
 
 Minister: Most of the dead were 12 to 16 years old 
 
 On a typical day, the Army Public School and Degree College is home to about 1,100 students and staff, most of them sons and daughters of army personnel from around Peshawar, though others attend as well. 
 
 Their nightmare began in late morning, when a car exploded behind the school. Pakistani education minister Muhammad Baligh Ur Rehman explained to CNN that the blast was a ruse, meant to divert the attention of the school's security guards. 
 
 It worked. 
 
 Gunmen got over the walls and walked through where students in grades 8, 9 and 10 have classes and fired randomly, said Dr. Aamir Bilal of Peshawar's Lady Reading Hospital, citing students. They came in with enough ammunition and other supplies to last for days and were not expecting to come out alive, according to a Pakistani military official. 
 
 Seventh-grader Mohammad Bilal said he was sitting outside his classroom taking a math test when the gunfire erupted. He fell into bushes before running to the school's gates to safety. 
 
 Ahmed, the 14-year-old student, remembered being in the school's auditorium when four or five people burst in through a back door "and started rapidly firing." After getting shot in his left shoulder, the ninth-grader lay under a bench.

 "My shoulder was peeking out of the bench, and somebody was following," Ahmed recalled. "They went into another room, (and when) I ran to the exit, I fell." 
 
 Bajwa told reporters that Pakistani security forces reached the school 15 minutes after the attack began. 
 
 They found, he said, "the children ... drenched in blood, with their bodies on top of each other." 
 
 Most of those killed were between the ages of 12 and 16, said Pervez Khattak, chief minister of Khyber Pakhtunkhwa province, of which Peshawar is the capital. But some adults in the school also were targets, like a 28-year-old office assistant who was shot and then burned alive, police official Faisal Shehzad said. 
 
 Violent past 
 
 Pakistan has seen plenty of violence, much of it involving militants based in provinces such as South Waziristan, North Waziristan and the Khyber Agency -- all restive regions in northwest Pakistan near Peshawar along its border with Afghanistan. 
 
 It is the home base of the TTP, an organization that has sought to force its conservative version of Islam in Pakistan. The group has battled Pakistani troops and, on a number of occasions, attacked civilians as well. 
 
 Peshawar, an ancient city of more than 3 million people tucked right up against the Khyber Pass, has often found itself in the center of it all. Militants repeatedly targeted the city in response to Pakistani military offensives, like a 2009 truck bombing of a popular marketplace frequented by women and children that killed more than 100 people. 
 
 And the Taliban hasn't hesitated to go after schoolchildren. Their most notable target is Malala Yousafzai, who was singled out and shot on October 9, 2012 as she rode to school in a van with other girls. The teenage girl survived and, last week, became the youngest recipient of the Nobel Peace Prize for her efforts to promote education and girls' rights in Pakistan and beyond. 
 
 Yousafzai was "heartbroken by this (latest) senseless and cold blooded act of terror in Peshawar," saying Tuesday that "innocent children in their school have no place in horror such as this." 
 
 "I call upon the international community, leaders in Pakistan, all political parties -- everyone -- (to) stand up together and fight against terrorism," the 16-year-old added in another statement. "And we should make sure that every child gets a safe and quality education." 
 
 Taliban: Revenge for killing of tribesmen 
 
 Still, even by Pakistan and the Taliban's gruesome standards, Tuesday's attack may be the most abominable yet. 
 
 This is the deadliest incident inside Pakistan since October 2007, when about 139 Pakistanis died and more than 250 others were wounded in an attack near a procession for exiled former Pakistani Prime Minister Benazir Bhutto, according to the University of Maryland's Global Terrorism Database 
 
 Even the Taliban in Afghanistan, with which the TTP is closely affiliated, criticized the "deliberate killing of innocent people, women and children (as being) against Islamic principles" and expressed condolences to the attack's victims, according to spokesman Zabiullah Mujahid. 
 
 It comes after peace talks between the Pakistan Taliban and Pakistan's government as recently as last spring. The government released 19 Taliban noncombatants in a goodwill gesture, in fact. 
 
 But talks broke down under a wave of attacks by the Taliban and mounting political pressure to bring the violence under control. 
 
 In September 2013, choir members and children attending Sunday school were among 81 people killed in a suicide bombing at the Protestant All Saints Church of Pakistan. A splinter group of the Pakistan Taliban claimed responsibility, blaming the U.S. program of drone strikes in tribal areas of the country. 
 
 And for the past few months, the Pakistani military has been conducting a ground offensive to clear out militants, spurring violence that's displaced tens of thousands of people and sparked deadly retaliations. 
 
 Khurrassani, the Pakistan Taliban spokesman, told CNN that the latest attack was revenge for the killing of hundreds of innocent tribesmen during repeated army operations in provinces including South Waziristan, North Waziristan and the Khyber Agency. 
 
 The TTP spokesman challenged that ordinary citizens were targeted, saying that five army vehicles are routinely stationed at the school. 
 
 "We are facing such heavy nights in routine," Khurrassani said, rationalizing the siege shortly before it ended. "Today, you must face the heavy night." ||||| Media playback is unsupported on your device Media caption The BBC's Mishal Husain was one of the first broadcasters to go inside the school 
 
 The Pakistani city of Peshawar is burying its dead after a Taliban attack at a school killed at least 132 children and nine staff. 
 
 New images from the school show the brutality of the attack, with pools of blood on the ground and walls covered in pockmarks from hundreds of bullets. 
 
 Mass funerals and prayer vigils for the victims are currently under way. 
 
 Gunmen had walked from class to class shooting students in the Pakistani Taliban's deadliest attack to date. 
 
 Prime Minister Nawaz Sharif declared three days of mourning over the massacre, which has sparked national outrage. 
 
 He also announced an end to the moratorium on the death penalty for terrorism cases, which correspondents say is a move aimed at countering a view held by many Pakistanis that many terror suspects end up evading justice. 
 
 World leaders have also voiced disgust at the attack, which even the Afghan Taliban have criticised.

 Separately, Pakistan's army says it launched air strikes at militants in the Khyber and North Waziristan areas, although it is not yet clear if this was a direct response to the school attack. An offensive against the militants has been going on since June.

 It is a very eerie atmosphere. These are premises that should be alive at a time of day like this to the sound of hundreds of children who studied here and began school as normal on Tuesday. But it is desolate now. 
 
 The army has been working through the night to clear the premises of explosives. 
 
 I am standing now at the bottom of the white stone steps that lead up to the auditorium. There are blood stains running right down the steps and towards the auditorium itself. 
 
 There is a child's shoe on one of the steps. The auditorium, where children were taking exams, was one of the places within the school grounds that the militants first targeted. 
 
 As I peer in now, the chairs that the children were sitting on are upturned, the place has been turned upside down and again I can see the blood stains on the floor right around me. 
 
 Mr Sharif also convened a meeting of all parliamentary parties in Peshawar to discuss the response. 
 
 Afghan role 
 
 Meanwhile, Pakistan's army chief General Raheel Sharif is in the Afghan capital, Kabul, on a surprise visit to discuss security co-operation aimed at tackling the Taliban insurgency. 
 
 Pakistani Taliban (TTP) leader Mullah Fazlullah is believed by the Pakistani authorities to be hiding in Afghanistan and media reports in Pakistan suggest the school attack may have been co-ordinated from Afghanistan. 
 
 But the TTP said the attack had been masterminded by its military chief in the Peshawar region, who it said had been in touch with the gunmen throughout the assault. 
 
 A TTP spokesman told the BBC they had deliberately killed older pupils and not targeted "small children". 
 
 BBC correspondents say the Taliban statement is being seen as damage limitation after the attack was universally condemned in Pakistan for its brutality. 
 
 The TTP also repeated its earlier claim that only six attackers were sent, contradicting official accounts that seven gunmen were killed. The militants say the attack was revenge for the army's campaign against them, and that they chose the school as a target because their families had also suffered heavy losses. 
 
 Scenes of devastation 
 
 Reporters visiting the school for the first time saw pools of blood marking the floor and torn notebooks, clothing and shoes among the debris. 
 
 "This is not a human act,'' military spokesman Major General Asim Bajwa said during a tour of the school, the Associated Press reports. "This is a national tragedy."

 Seven Taliban attackers wearing bomb vests cut through a wire fence to gain entry to the school, before launching an attack on an auditorium where children were taking an exam. 
 
 Gunmen then went from room to room at the military-run school, shooting pupils and teachers where they found them in a siege that lasted eight hours, survivors say. 
 
 A total of 125 people were wounded at Peshawar's Army Public School, which teaches boys and girls from both military and civilian backgrounds. All seven attackers were killed, while hundreds of people were evacuated.

 Mohammad Hilal, a student in the 10th grade, was shot three times in his arm and legs when the gunmen stormed the school auditorium. 
 
 "I think I passed out for a while. I thought I was dreaming. I wanted to move but felt paralysed. Then I came to and realised that actually two other boys had fallen on me. Both of them were dead," he told the BBC. 
 
 Zulfiqar Ahmad, 45, the head of the mathematics department who was shot four times during the attack told the BBC he did not believe any of the 18 students in his class had survived. 
 
 The victims are also being mourned elsewhere, with India's parliament observing a minute's silence in their honour. 
 
 India's Prime Minister Narendra Modi offered his country's "deepest condolences". 
 
 Mr Sharif pledged to avenge a "national tragedy unleashed by savages". 
 
 Malala Yousafzai, the 17-year-old who was shot by the Pakistani Taliban for championing girls' rights to education, also condemned "these atrocious and cowardly acts".

 Prayer vigils were held across the nation and in other schools, students spoke of their shock at the carnage in the city of Peshawar, where seven Taliban gunmen, explosives strapped to their bodies, scaled a back wall using a ladder to get into the Army Public School and College in the morning hours on Tuesday. 
 
 Students were gunned down and some of the female teachers were burned alive. The attack was the deadliest slaughter of innocents in the country and horrified a nation already weary of unending terrorist assaults. Army commandos fought the Taliban in a day-long battle until the school was cleared and the attackers dead. 
 
 The government declared a three-day mourning period, starting Wednesday. Overnight, the body of the school principal, Tahira Qazi, was found among the debris from the rampage. Her death raised further the earlier reported death toll of 141. 
 
 Some of the funerals were held overnight, but most of the 132 children and 10 school staff members killed in the attack were to be buried Wednesday. Another 121 students and three staff members were wounded. 
 
 "They finished in minutes what I had lived my whole life for, my son," said laborer Akhtar Hussain, tears streaming down his face as he buried his 14-year-old, Fahad. He said he had worked for years in Dubai to earn a livelihood for his children. 
 
 "That innocent one is now gone in the grave, and I can't wait to join him, I can't live anymore," he wailed, banging his fists against his head. 
 
 The Taliban said the attack was revenge for a military offensive against their safe havens in the northwest, along the border with Afghanistan, which began in June. Analysts said the school siege showed that even diminished, the militant group still could inflict horrific carnage. 
 
 The attack drew swift condemnation from around the world. President Barack Obama said the "terrorists have once again showed their depravity." 
 
 Pakistan's teenage Nobel Peace laureate Malala Yousafzai — herself a survivor of a Taliban shooting — said she was "heartbroken" by the bloodshed. 
 
 Even Taliban militants in neighboring Afghanistan decried the killing spree, calling it "un-Islamic." 
 
 Pakistani Prime Minister Nawaz Sharif pledged to step up the campaign that — along with U.S. drone strikes — has targeted the militants. 
 
 "We will take account of each and every drop of our children's blood," said Sharif, who rushed to Peshawar shortly after the attack to offer support for the victims. 
 
 In neighboring India, which has long accused Pakistan of supporting anti-India guerrillas, schools on Wednesday observed two minutes of silence for the Peshawar victims at the urging of Prime Minister Narendra Modi, who called the attack "a senseless act of unspeakable brutality."

– "We will take revenge for each and every drop of our children's blood," Pakistani Prime Minister Nawaz Sharif vowed as funerals began for 132 children slaughtered in a Taliban attack on a school in Peshawar yesterday. Sharif said there would be three days of national mourning for the massacre at a military-run school, in which 10 staff members were killed, as well as all seven attackers, the BBC reports. Sharif also said he would reinstate the death penalty for terrorism. More: The attack was condemned worldwide, with Pakistan's archrival India, whose president called the attack "a senseless act of unspeakable brutality," observing two minutes of silence in schools, reports the AP. Even the Taliban in Afghanistan spoke out against the atrocity, calling it "un-Islamic." There are signs that the attackers—some of whom reportedly spoke in Arabic to each other—had intended to stay for a long siege, with some of them carrying stores of food, the New York Times reports. A security official, however, says they never attempted to take any hostages. "They were there to kill, and this is what they did," he says. One official tells the Guardian that the attackers accessed the school via an unguarded back wall. They may have parked their vehicle next to it and then just climbed on the roof of the vehicle and over the wall. A Pakistani Taliban spokesman says the attack was revenge for a military offensive against the militants in areas including North Waziristan, where he says hundreds of innocent people have been killed. The country's defense minister tells CNN that the country will not back off from the offensive, but that the slaughter is another example of the sacrifices Pakistan has made in its battle against the militants. "The smaller the coffin, the heavier it is to carry," he says. "It's a very, very tragic day."
