CAIRO (Reuters) - U.S. Secretary of State Mike Pompeo visited Iraq on Wednesday, where he met with American troops and Iraqi leaders to reassure them about a U.S. military withdrawal from Syria and warn that Iran remains a regional security threat.

The visit, which U.S. officials declined to confirm until Pompeo left Iraq, came on the second day of a tour also taking in Jordan, Egypt, Bahrain, Qatar, United Arab Emirates, Saudi Arabia, Kuwait and Oman.
