Nearly 150 people, most of them, children, were killed when armed men opened indiscriminate fire in the army-run school.
The deadliest act of terrorism in Pakistan's history had sent everlasting shockwaves across the country.
At the eighth anniversary of the tragic incident, parents of the martyred students blocked Khyber Road, bringing the traffic to a halt.
The protesters walked to Warsak Road and attempted to talk to the Corps Commander, Peshawar but were obstructed by police.
Talking to media, one of the parents complained of inaction by the state despite the passage of years following the incident.
They went on to add that no one from the government, or other high-ups, attended the event held in remembrance of the tragedy.
