The American Wall Street Journal said that the assistance provided by Moscow in the attacks that disrupted global trade shows how the Kremlin seeks to involve the United States in the Middle East.

Attack methods include posing as Yemeni officials, using cruise missiles, anti-ship ballistic missiles, waterborne improvised explosive devices, drones, and mines.

The repercussions of the Red Sea traffic crisis due to attacks by the Houthi group on passing ships continue to affect maritime shipping, supply chains and the cargo shipping industry.

Of the roughly 100 ships targeted, according to a tally by the Joint Maritime Information Center, run by a Western naval coalition, only a handful of attacks have caused casualties or serious damage.

A senior US official said that members of the Russian military intelligence service are working in Houthi-controlled territory in Yemen in an advisory role.

Repairs of three undersea communications cables damaged in the Red Sea finally began in February, even as Houthi militants escalated their attacks on ships in the region.
