Houthi attacks on ships are giving the rebels and Iran intel on how to hunt down and strike naval targets, war experts say

• The Houthis have spent the past few months lobbing missiles and drones at ships off Yemen's coast.
• These threats have not hit US Navy ships in the region, but they have struck merchant vessels.
• War experts say these attacks are giving Iran and the rebels, Tehran's proxies, valuable data.

After months of constantly firing missiles and drones at ships off the coast of Yemen, the Houthis are showing no signs of ending their relentless provocations.
