Russia provided targeting data for Yemen’s Houthi rebels as they attacked Western ships in the Red Sea with missiles and drones earlier this year, helping the Iranian-backed group assault a major artery for global trade and further destabilizing the region. The Houthis, which began their attacks late last year over the Gaza war, eventually began using Russian satellite data as they expanded their strikes, said a person familiar with the matter and two European defense officials. The data was passed through members of Iran’s Islamic Revolutionary Guard Corps, who were embedded with the Houthis in Yemen, one of the people said.
