Iraq is suffering its worst unrest in years and authorities have so far failed to check daily violence targeting both civilians and security forces.
There have now been at least six attempts to kill Nujaifi in less than a year, showing that even the most senior official in the northern province of Nineveh -- one of the most dangerous in Iraq -- is vulnerable to attack.
Two roadside bombs exploded near Nujaifi's convoy in Nineveh's capital Mosul, wounding two provincial councillors but leaving the governor unharmed, a police major and a hospital employee said.
Militants are also said to extort money from business owners in Mosul, helping to fund their activities in Iraq and neighbouring Syria.
Attacks killed three civilians and two army officers in Nineveh today, while 11 militants died during an assault on an army position in the province.
Gunmen shot dead a woman near her home in Baghdad, while one person was killed by a magnetic "sticky bomb" on a vehicle in Taji, north of the capital.
Anti-government fighters also control all of Fallujah, east of Ramadi and just a short drive from Baghdad.
The defence ministry said that security forces killed 13 militants today in Anbar province, where both Ramadi and Fallujah are located.
