Georgian prosecutors say the charge against Vladimir Arutyunian stems from the killing of a Georgian Interior Ministry security officer during a gunfight that erupted as police tried to capture him Wednesday.
The United States expressed sympathy over the death of the officer, and lauded the bravery and dedication of Georgian authorities in taking the man into custody.
Georgian officials say Mr. Arutyunian confessed to throwing the grenade at President Bush, who was addressing tens of thousands gathered in Tbilisi's Freedom Square.
The grenade landed in front of the stage but failed to explode.
