London: Nobel Peace Prize 2014 winner Malala Yousafzai on Tuesday condemned the Peshawar attack and said that she is 'heartbroken by senseless and cold-blooded act of terror'.
“I am heartbroken by senseless and cold-blooded act of terror,” Malala said, BBC reported.
"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."
17-year-old Malala, who now lives in Britain, became a global icon after she was shot and nearly killed by the Taliban in her native Pakistan in October 2012 for insisting that girls had a right to an education.
At least 124 students were among the 126 people killed when heavily armed terrorists launched a brazen attack on an army-run school in Pakistan's Peshawar city.
The horrifying attack comes amidst political turmoil in the country and just a day after the hostage crisis at a cafe in Australia's Sydney city.
Around four to five terrorists first set a vehicle on fire and then stormed the Army Public School building located at Warsik Road in Peshawar, the capital of Pakistan's Khyber-Pakhtunkhwa province, ARY news reported.
Television footage showed the school children shocked and in tears. Some of them had blood on their faces. One of the students was carried away on a stretcher while another leaned onto a security personnel who helped him away.
The frightened children recalled the horror.
Over 500 students and teachers were trapped inside the building, with eyewitnesses saying they saw some of the wounded lying in the corridors.
A school teacher said that around 1,400 to 1,500 students study in the school.
Soon after the terrorists struck, a suicide bomber among them blew himself up outside the school auditorium.
Unconfirmed reports said that the auditorium was packed with students who were taking their exams.
The students were initially under the impression that it was yet another army drill and the horror sank in only after they saw school mates being hit by bullets.
The school teachers apparently tried to shepherd the children to safety. Some were able to flee soon after the attack began at noon, while a few others were taken out to safety by the security personnel who responded promptly.
The Tehreek-i-Taliban Pakistan (TTP) has claimed responsibility and called it a revenge attack for the army operations in North Waziristan.
The guerrillas carried out the attack on the school that is normally well guarded and is considered secure.
Inter-Services Public Relations (ISPR) has confirmed that the children and staff are being evacuated from the building.
