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.
A candlelit vigil has been held in Lahore, Pakistan, in honour of the victims of the Easter Sunday suicide bombing.
At least 70 people -including 29 children - were killed in the blast, which has been claimed by a faction of the Pakistani Taliban.
Civil rights activists and lawyers gathered at the vigil, calling for unity and holding placards condemning the bombing and reading: 'Terrorism has no religion' and 'No to Talibanization'.
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.
