WASHINGTON— The United States imposed terrorism sanctions on Iran's envoy to the Houthis on Tuesday, a step possibly aimed at pressuring the group to reach an accord to end the five-year war in Yemen.
The U.S. Treasury described Hasan Irlu as an official of Iran's elite Quds Force, the overseas arm of Iran's Islamic Revolutionary Guard Corps and a pillar of Iranian efforts to project its power in Yemen, Syria, and elsewhere.
Confirming a Reuters report, the Treasury also blacklisted Iran's Al-Mustafa International University, alleging it uses its foreign branches as a Quds Force recruitment platform for intelligence collection and operations.
It also imposed sanctions on Yousef Ali Muraj, an Iran-based Pakistani the Treasury accused of supporting Quds Force efforts to carry out operations in the Middle East and the United States.
Irlu, Muraj, and the university were all targeted under U.S. Executive Order 13224, which allows Washington to block the assets of foreign individuals and entities that commit, or pose a significant risk of committing, acts of terrorism.
The Quds Force is itself a U.S.-designated foreign terrorist organization.
The decision to target Irlu appears in part a signal to the Iran-backed Houthis, who have been battling a Saudi-led military coalition in Yemen since 2015.
The United Nations is trying to revive peace talks stalled since late 2018 to end a war that has been in a military deadlock for years, with the Houthis holding the capital, Sanaa, and most big urban centers.
Washington and Saudi Arabia see the Yemeni group as an extension of Iranian influence in the region.
Kirsten Fontenrose, a former White House National Security Council Gulf expert now at the Atlantic Council think tank, described the sanction as partly a warning to the Houthis that they may be next.
"Come to the table, have these political talks in seriousness, and recognize that this designation is on your doorstep," she said of the U.S. message to the Houthis. "We are taking another step closer."
As a result of Tuesday's action, all property of those designated, as well as of any entities 50 percent or more owned by them, that fall under U.S. jurisdiction are blocked, and U.S persons are generally prohibited from dealing with them.
In addition, foreign banks that knowingly facilitate significant transactions for them, or people who provide material support to them, risk losing access to the U.S. financial system or having their own property blocked.
