(Bloomberg) -- The US imposed fresh sanctions on Iran over its April 13 strike on Israel, targeting 16 people and entities including a company that helped make engines for the type of drones launched in the barrage.

The sanctions also targeted subsidiaries of the Iranian automaker Bahman Group, which the Treasury Department said has supported Iran’s Islamic Revolutionary Guards Corps, as well as customers of a steel company that brings in billions of dollars of revenue for Iran every year.

“Let it be clear to all those who enable or support Iran’s attacks: The United States is committed to Israel’s security,” President Joe Biden said in a statement. “We are committed to the security of our personnel and partners in the region. And we will not hesitate to take all necessary action to hold you accountable.”

The US and its allies are trying to demonstrate to Iran that there will be consequences for the attack on Israel, which saw Tehran launch some 300 drones and missiles, almost all of which were shot down before they hit their targets. At the same time, allied nations have implored Israel not to retaliate, fearing that a direct strike on Iran could touch off a regional war.

Even so, any impact of the sanctions announced Thursday is likely to be limited. Iran’s drone program, the IRGC and Bahman group have been under sanctions for years, and those restrictions failed to deny Iran funding to advance its production of they types of weapons used in last weekend’s barrage against Israel. The IRGC is also designated a terrorist group, meaning it’s already severed from the US financial system.
