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.
My brothers and sisters, today again I am here to renew my commitment that we will avenge every drop of the blood of our martyred people and we are doing that, and we will not rest until we have accounted for everything to the end.
We will not let them raise their heads again, we will not allow them to play the lives of the people of Pakistan. This is my resolve, this is my government's resolve and this is the resolve of the 200 million people of Pakistan.
God willing, no terrorist can put a dent in our resolve.
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.
