Iran’s semi-official Tasnim news agency reported on Wednesday that Tehran’s sea-launched ballistic missile Ghadr has been made available to Yemen’s Houthis.

“Iran’s sea-launched ballistic missile, named Ghadr, now has been made available to Yemen’s (Houthi) fighters,” reported Tasnim, which is believed to be affiliated with Iran’s elite Revolutionary Guards.

“Now, the missile… has become a weapon capable of presenting serious challenges to the interests of the United States and its main ally in the region, the Zionist regime,” Tasnim said.

Iran’s foreign ministry did not immediately respond to a request for comment.

Iran supports the Houthis but had previously repeatedly denied arming the group.

The Houthis have been attacking shipping lanes in and around the Red Sea in what they say is a show of support for Palestinians amid the war between Israel and Hamas, impacting a shipping route vital to trade.

They have also fired ballistic missiles and drones at the southern Israeli city of Eilat.

According to the US Office of the Director of National Intelligence, Iran is armed with the largest number of ballistic missiles in the region. It is also a major producer of drones.

Last month, Iran launched more than 300 projectiles at Israel, comprising 170 drones, 30 cruise missiles, and 120 ballistic missiles, in an unprecedented attack.
