"The President [Obama] urged President Erdogan to take additional steps to deescalate tensions with Iraq, including by continuing to withdraw Turkish military forces, and reinforced the need for Turkey to respect the sovereignty and territorial integrity of Iraq," the release said on Friday.
The two leaders have also agreed to cooperate with the Iraqi government on reducing tensions and coordinating the anti-Daesh campaign.
Obama and Erdogan also discussed support to the so-called moderate Syrian opposition fighting the terrorists.
On December 4, Turkey deployed about 150 troops and 25 tanks to the Bashiqa camp, without Baghdad’s approval.
Turkey started withdrawing its troops on December 14, after Iraq had officially filed a complaint with the UN Security Council, calling on the United Nations to ensure an immediate withdrawal of the Turkish forces from its country's territory.
