A Pakistani police officer says the death toll from the suicide bombing near the country's border with India has risen to 60.

Nadeem Khokhar says Sunday's attack also wounded more than 100 people, who are still in hospital.

The bomber set off his explosives near a Pakistani paramilitary checkpoint on the outskirts of the city of Lahore, when hundreds of people were returning from watching an army parade.

Archrivals Pakistan and India hold daily parades and flag-flying ceremonies on their respective sides of the border, drawing thousands of spectators.

The parades are meant to be a show of strength between the foes — the two nuclear-power nations have fought three wars since they gained independence in 1947.

The Pakistani Taliban splinter group Jamatul Ahrar has claimed responsibility for the attack.
