The aim is to drive al-Qaida in Iraq out of Mosul, the capital of Nineveh Province and a stronghold of the group, CNN reported.
A U.S. military source told CNN that more Iraqi troops would be moving into Mosul soon.
"Iraqis are taking the lead in this action," the source said.
Also present at the meeting were the Iraqi defense and interior ministers, Abdul Qadir Mohammed Jassim and Jawad al-Bolani, and the top U.S commanders, Gen. David Petraeus and Lt. Gen. Raymond Odierno.
The meeting came the day after bombings in two Baghdad markets. Investigators say the explosives were strapped to two mentally handicapped women and detonated remotely.
