A device, possibly a grenade, landed undetonated about 100 feet from where President Bush was speaking Tuesday in Tbilisi, in the former Soviet republic of Georgia, according to media reports. No one was injured and the president was back at the White House Tuesday evening. The story was later disputed.
The ABC News Web site had reported that local Georgian police told the U.S. Secret Service that the device was thrown as the president spoke in Freedom Square in the Georgian capital. It hit someone and fell to the ground some 100 feet from the stage, the Secret Service said, according to ABC.
Georgian authorities later called the original account a lie. ABC News later reported that Guram Donadze, a Georgian interior ministry spokesman, said nothing was thrown near the president. But he later said an announcement about the reports would be made Wednesday.
The appearance was the final stop in the president's four-nation tour commemorating the 60th anniversary of the end of World War II in Europe.
