More than 50 people have been killed and at least 100 injured in a suicide bombing close to Pakistan’s only border crossing with India.
The blast hit near the checkpoint at the Wagah border crossing, near Lahore.
The Pakistani Taliban told the BBC that it had carried out the attack, although another militant group, Jundullah, also said it was responsible.
At least 15 people were badly injured, and officials said three members of the Pakistani border force had died.
The Wagah crossing is a high-profile target, with large crowds gathering every day to watch an elaborate flag-lowering ceremony as the border closes.
