A woman jumped the barriers in St. Peter's Basilica and knocked down Pope Benedict XVI at the start of Christmas Eve Mass, but the 82-year-old pontiff got up unhurt and proceeded as planned with Thursday's service.

Witness video obtained by The Associated Press showed a woman dressed in a red hooded sweat shirt vaulting over the wooden barriers that cordoned off the basilica's main aisle and rushing toward the pope before being swarmed by bodyguards.

The video showed the woman grabbing the pope's vestments as she was taken down by guards, with Benedict then falling on top of her.
