Pakistan has held 216 suspects after a major sweep by the military and the police saw more than 5,000 detained over the Easter Sunday suicide bomb attack.
Prime Minister Nawaz Sharif vowed to crack down on Islamist militants in the country after the attack in Lahore claimed the lives of more than 70 people, including 29 children.
Pakistan will "avenge every drop of blood" spilled in a suicide bomb attack at a public park on Easter Sunday, the country's Prime Minister has vowed.
In an emotional televised address, Nawaz Sharif condemned a series of terrorist strikes across Pakistan in recent months - the latest of which left at least 70 people, including 29 children, dead and hundreds more injured.
He said the army would forge on with its operation targeting militant hideouts, and said police would hunt down extremists.
The impact of the operations to date were the reason behind the terrorists choosing "soft targets" such as playgrounds and schools, he added.
Users thousands of miles from Lahore have reported being asked to check in safe following the bombing which killed at least 65 people.
Police say at least 280 other people are injured, and most of the dead and injured are women and children.
