The blast took place in the mosque inside a Pakistani police headquarters, after which Pakistan was put on high alert by the government.
As per the footage release, people in huge numbers are seen gathered around the mosque, as piles of debris lie on the ground and the area appeared cordoned off by the barrier tape.
The suicide bombing, which ripped the mosque during noon prayers and led to the collapse of a wall on the worshippers, was claimed by the Tehreek-e-Taliban Pakistan (TTP).
The officials carried out a frantic rescue mission to save the policemen buried in the debris after an entire wall and roof of the mosque were blown out in the blast. Peshawar police chief Muhammad Ijaz Khan said, “Many policemen are buried under the rubble. Efforts are being made to get them out safely.”
Badly-wounded survivors were seen emerging from the wreckage as officials ferried away the bodies of the dead in the ambulances. "It's an emergency situation," hospital spokesperson Muhammad Asim Khan said.
Pakistan’s Prime Minister Shehbaz Sharif said that this is the worst blast the city has witnessed since the suicide attack that took place in March, last year.
"Terrorists want to create fear by targeting those who perform the duty of defending Pakistan," PM Sharif said in a statement. "Those fighting against Pakistan will be wiped out from the face of the earth,” he added.
