US-appointed Iraqi Governing Council member Salama al-Khufaji survives an ambush as violence claims Iraqi and foreign lives elsewhere in the country.
Al-Khufayi's son, Ahmad, however, did not survive the attack and reports indicated he drowned on Thursday after his car crashed in a river.
"The head of Khufaji's protection unit told our correspondent in Baghdad that her son, Ahmad, drowned when the car in which he was travelling fell in a river," Aljazeera television reported
A bodyguard was also killed.
Salam al-Khufaji herself had not been hurt in the attack.
An Iraqi official in Baghdad told AFP she escaped unharmed when her convoy came under attack at Yusufiyah, 20 kilometres south of the Iraqi capital, as she returned from a trip to Najaf.
According to medical sources at Al-Yarmuk hospital in Baghdad, two bodyguards were also injured in the incident.
