WASHINGTON (CNN) -- U.S. officials are investigating a report that an apparent hand grenade landed about 100 feet from where President Bush was speaking Tuesday in Tblisi, the capital of Georgia, a Secret Service spokesman said.
The Secret Service has not yet confirmed whether the object was a real grenade and if so, whether the pin had been pulled, said spokesman Jim Mackin.
"We have not seen the reported device," he said.
No explosion was reported.
Mackin said Georgian officials alerted their U.S. counterparts about the incident several hours after Bush departed the former Soviet republic, where he received an enthusiastic welcome in a public square in the capital.
According to the account by Georgian security officials, the grenade hit an individual and fell to the ground, Mackin said.
At that point, security officers recognized the device and removed it, he said. No further details were available.
The FBI and State Department are also investigating the incident, Mackin said.
In his speech, Bush told a crowd of tens of thousands that Georgia is proving to the world that determined people can rise up and claim their freedom from oppressive rulers.
Bush's speech was the last event of his five-day, four-nation tour marking the end of World War II in Europe.
