Russia has been providing critical targeting data to Yemen's Houthis rebels to aid in their attacks on Western ships in the Red Sea, the Wall Street Journal reported on Thursday.

The Houthis, who maintain control over Yemen's capital and much of the population, have attacked international shipping vessels in the Red Sea since November of 2023. The drone and missile strikes began as a sign of solidarity with Palestinians following the Oct. 7 massacre by Hamas on Israeli civilians and the ensuing war in Gaza.

Two European defense officials and a person familiar with the matter told the outlet that the Iranian-backed Houthis have been using Russian satellite data to expand their attacks. The data was moved through members of Iran's Islamic Revolutionary Guard Corps, who were embedded with the Houthis in Yemen, according to the source.
