Washington: US President George W Bush on Friday called Iranian President Mahmoud Ahmadinejad, who had questioned the existence of the Holocaust and suggested Israel be moved to Europe, an "odd guy."
"He's a odd guy," Bush said in an interview to be broadcast on PBS television later on Friday. "I'm worried about a theocracy," He added.
Ahmadinejad earlier this week triggered international condemnation for saying that the Holocaust was a myth.
It was the latest in a series of controversial comments since he was elected in June.
He has also suggested Israel be moved to Europe, and that Israel must be "wiped off the map."
The United States has repeatedly raised concerns about Iran's nuclear programme, accusing Tehran of seeking nuclear weapons.
Iran insists its nuclear programme is for generating electricity.
"One of the real issues we're gonna have to deal with, and are dealing with, is Iran.
Bush said Iran supports militant group Hizbollah, which he said was trying to derail the Middle East peace process.
One way to encourage reformers in Iran is to have new democracies in Afghanistan and Iraq, Bush said.
"So the stakes in Iraq are beyond just making sure that Iraq is not a safe haven for al Qaeda," he said.
