Reuters reported that Iranian weapons and agents still pose a threat to U.S.-led forces in Iraq, a U.S. military spokesman said on Sunday, despite a recent softening in tone by U.S. officials towards Washington’s bitter foe.

“We’re still seeing a large number of Iranian-made weapons still exist here in Iraq,” U.S. military spokesman Rear Admiral Gregory Smith told a news conference, adding that “individuals” coordinating and carrying out attacks were still in the country.

Washington and the U.S. military in Iraq accuse Iran of arming, training and funding Shi’ite militias in Iraq, a charge Tehran denies.

U.S. embassy spokesman Phil Reeker said in a press conference that it is not clear yet whether Iran has had any role in reduction of violence in Iraq or not.
