There's no tragedy in life like the death of a child. Things never get back to the way they were.

On 16 December 2014, the heart-wrenchingly tragic incident took place on this day. This day will be the blackest day in the history of Pakistan.

On this day, six gunmen affiliated with the Tehrik-i-Taliban Pakistan (TTP) conducted a terrorist attack on the Army Public School in Peshawar. The terrorists began their attack in mid-morning when they accessed the large compound by scaling a wall. According to some reports, they bombed their own vehicle to create a distraction for school guards. Entering the main assembly hall, where a large group of students was taking a lesson in first aid, they proceeded to shoot indiscriminately. The attackers, who were armed with grenades and automatic rifles, then went to the classrooms, where they concentrated their fire on teachers and older children. According to official sources, they sought only to kill and made no attempt to take hostages. The militants opened fire on school staff and children, killing 149 people including 132 schoolchildren, ranging between eight and eighteen years of age making it the world's fourth deadliest school massacre.

A rescue operation was launched by the Pakistan Army's Special Services Group (SSG) special forces, who killed all six terrorists and rescued 960 people. Tehrik-e-Taliban claimed responsibility for the attack, saying it was in revenge for a ferocious army offensive – named Zarb-e-Azb – that has been underway in tribal areas since the summer and has left an estimated 1,000 militants dead and tens of thousands of people displaced. According to various news agencies and commentators, the nature and preparation of the attack were very similar to that of the Beslan school hostage crisis that occurred in the North Ossetia–Alania region of the Russian Federation in 2004. 

On 2 December 2015, Pakistan hanged four militants involved in the Peshawar massacre, whereas the mastermind of the attack, Omar Khorasani, was killed in a drone strike in eastern Afghanistan on 18 October 2017. The Supreme Court of Pakistan upheld the death sentences of two more convicts involved in the attack in the Said Zaman Khan v. Federation of Pakistan case on 29 August 2016.

The smallest coffins are the heaviest. We can't forget the martyrs of APS Peshawar.
