BAGHDAD, Iraq (CNN) -- Iraq's President Jalal Talabani has fallen ill and was flown to neighboring Jordan for treatment, a statement from his office said Sunday.
"There is no need to worry," the statement said.
A senior U.S. military official said the United States' understanding is that Talabani, 73, had a heart attack.
Talabani's son Qubad Talabani told CNN his father did not have a heart attack.
If this man dies, I am of the opinion that whatever is left of the Iraqi goverment wil die with him.
