US intelligence suggests Iran is "deeply involved" in Red Sea attacks on commercial ships

The US on Friday released newly declassified intelligence that suggests Iran has been “deeply involved in planning the operations against commercial vessels in the Red Sea,” National Security Council spokesperson Adrienne Watson told CNN.
The Iran-backed Houthi rebels have launched more than 100 attacks against about a dozen commercial and merchant ships transiting the Red Sea over the past four weeks, CNN previously reported. The newly declassified intelligence suggests that “Iranian support throughout the Gaza crisis has enabled the Houthis to launch attacks against Israel and maritime targets, though Iran has often deferred operational decision-making authority to the Houthis,” Watson said.
On Tuesday, a senior US military official said the Iranians are operating in the Red Sea when asked whether Iran is helping the Houthis select targets. But that official said the Houthi attacks have been broadly indiscriminate.
“Iran has the choice to provide or withhold this support, without which the Houthis would struggle to effectively track and strike commercial vessels navigating shipping lanes through the Red Sea and Gulf of Aden,” Watson said.

The intelligence also suggests that the Iranians have provided monitoring systems to the Houthis that allow them to operate in the maritime space, Watson said.
“Iranian-provided tactical intelligence has been critical in enabling Houthi targeting of maritime vessels since the group commenced attacks in November,” she added.
The drones and missiles the Houthis have been using for the attacks were also provided by Iran, Watson said, as part of Iran’s arming of the rebel group since 2015.
The US this week launched Operation Prosperity Guardian, a maritime coalition aimed at beefing up security in the southern Red Sea. More than 20 nations have signed on to the initiative so far, the Pentagon said Thursday.
