The President of Iraq, Ghazi Yawar, has said the UN should decide whether the elections scheduled to take place on 30 January should go ahead in the light of recent violence.
Mr Yawar said the elections would fail if the insurgency kept a significant number of Iraqis away from voting stations.
Baghda governor is assassinated
Earlier, Baghdad governor Ali Radi al-Haidari was assassinated by gunmen in the capital.
A car carrying the gunmen drove up and opened fire on Mr al-Haidari and his bodyguard in their car, killing both of them. He had survived a previous assassination attempt last September.
Elsewhere, 11 people were killed, eight of them policemen, and up to 60 injured in a truck bombing outside the command post of special Iraqi forces in western Baghdad.
Responsibility for both atrocities was claimed by the Al-Qaida group in Iraq, which is led by Iraq's most wanted terrorist Abu Musab al-Zarqawi, via a statement posted on the internet.
