The Turkish gunman who shot and wounded John Paul II in 1981 laid white flowers Saturday on the saint's tomb in St. Peter's Basilica, Vatican officials said. A Vatican spokesman, the Rev. Ciro Benedettini, said the surprise visit by Mehmet Ali Agca, believed to be his first time in the Vatican since the assassination attempt, lasted a few minutes. As with other flowers left by visitors to the tomb, the blossoms were later removed by basilica workers.
