The United States designated the head of Iran's central bank as a terrorist on Tuesday, accusing him of funneling money to Hezbollah, the Iran-backed militant group.

The Treasury Department said it had imposed sanctions on Valiollah Seif, the bank's current governor, and another senior official, Ali Tarzali, the assistant director of the bank's international department, labeling them both as "specially designated global terrorists."

That deal, reached in 2015 and formally known as the Joint Comprehensive Plan of Action (JCPOA), sought to curb Iran's pursuit of a nuclear arsenal by providing significant sanctions relief for the country.

Trump had threatened for more than a year to abandon the deal. He argued it failed to address Iran's activities beyond its nuclear pursuits, such as its support for groups like Hezbollah, which is considered a terrorist organization by the U.S.
