A faction of the Taliban has claimed responsibility for a suicide bomb attack in Pakistan, which killed at least 65 people and injured 300.

The explosion took place in the parking area of Gulshan Iqbal Park, just a few feet away from some children's swings.

The area was crowded at the time because Christians were gathering to celebrate the Easter holiday.

Many families were leaving the park when the blast occurred.

The death toll is expected to rise as many of those injured are in a critical condition.
