A devastating suicide attack at the entrance of the Wagah border parade venue on Sunday killed at least 60 people, including 10 women and seven children, and left more than 110 injured.

A young suicide bomber blew himself up at the entrance of the parade complex soon after the completion of the flag-lowering ceremony, which is a daily feature at Wagah.

Three officers of the Punjab Rangers and seven members of a family were among the dead in the explosion which was so loud that the bang was heard some 10 kilometres from the border.
