British Prime Minister David Cameron has promised help for Pakistan after a terrorist bombing killed 65 people in a park in Lahore.
The device, carried by a suicide bomber, was detonated near children's rides while families celebrated Easter on Sunday.
A breakaway Pakistani faction of the Taliban has claimed responsibility for the carnage and said it had deliberately targeted the Christian community.
More than 300 were injured in the attack, mainly women and children.
Cameron, who used his Easter message to urge Britons of all faiths to stand up for Christian values, said he was shocked by the attack.
"My thoughts are with the families and friends of the victims. We will do what we can to help," the PM posted on his Twitter feed.
