Speaking at a press conference, Nujaifi called for firm measures to stamp out "terrorism" in Fallujah, but warned against resorting to indiscriminate shelling, which, he said, tended to cause enormous human casualties.
On Saturday, Nujaifi returned from Washington where he had held talks with US President Barack Obama on the current security situation in Iraq.
Iraq's western Anbar province – of which Fallujah is a main city – has been rocked by violence since late December, when security forces dismantled a months-old anti-government sit-in outside Ramadi.
The sit-in was meant to protest perceived anti-Sunni discrimination by the Shiite-dominated government of Prime Minister Nouri al-Maliki.
"We must provide help to those who have been displaced and work on winning the hearts of Anbar residents," al-Nujaifi said, going on to call for legal action against countries that "support terrorism."
Two police personnel were gunned down by militants in Baqubah in the northern province of Diyala, a police source told Anadolu Agency.
An army soldier was killed in a militant attack on a checkpoint in western Mosul in western Iraq.
Three policemen were killed and a pro-government tribesman was injured in a drive-by shooting in Samarra, west of Tikrit in northern Iraq, a police source said.
Meanwhile, eight civilians were killed and 39 others injured in army shelling of residential areas in the western city of Fallujah.
Two fighters were also killed and four others injured in clashes between army forces and militants from the Qaeda-linked Islamic State of Iraq and Levant in the western Anbar province.
