Abadi did not directly reject the deployment, of which US Secretary of State John Kerry said Baghdad had been informed before the announcement, but he insisted that any operations be coordinated with the Iraqi government.
The presence of American ground forces is a contentious issue in Iraq, where the United States fought a nearly nine-year war, and it is politically expedient for Abadi to distance himself from the deployment.
"There is no need for foreign ground combat forces in Iraqi territory," Abadi said in a statement released late Tuesday in which he praised the performance of Iraqi special forces.
