Jordan’s king told a delegation of US congressmen Sunday that he fears the turmoil in Iraq could spill over into the entire region.

During the meeting in Amman, Abdullah II said that Jordan is working to preserve Iraq’s territorial integrity and the unity of its people, Ynet reported.

He added that any solution to the problems in the war-torn country must involve all of the people of Iraq.

Abdullah’s comments put him at odds with Israel on Iraq’s future. Prime Minister Benjamin Netanyahu on Sunday called for full independence for Iraq’s northern Kurdish region, echoing earlier statements by President Shimon Peres.

Abdullah’s comments came as the Iraqi army continued to attack jihadist forces that have recently seized large areas of the country north of Baghdad. In the biggest operation yet against the Islamic State of Iraq and the Levant, troops backed up by tanks and helicopter gunships battled to retake the city of Tikrit.

Tikrit is one of two major urban centers that fell to insurgents earlier this month during their lightning offensive across the country’s north and west.
