Florida Sen. Mel Martinez says the C130 E wasn't hit and no one was hurt, but three rocket-propelled grenades were believed to be fired at it as it left Baghad airport, carrying Martinez and a congressional delegation.
The Republican and staunch backer of President Bush said the incident did little to shake his faith that Bush's troop surge is making progress in Iraq.
"It's isolated incidents," he said. "These people are out there trying to kill and maim, but that doesn't diminish in the least what are signs of military progress and political reconciliation."
More details to come.
