U.S. conducts another strike against Houthi

Since mid-November, the Houthis, a Yemeni rebel group backed by Iran, have launched dozens of attacks on ships sailing through the Red Sea and the Suez Canal, a crucial shipping route through which 12 percent of world trade passes.

The United States and a handful of allies, including Britain, struck back, carrying out missile strikes on Houthi targets inside Yemen early Friday local time and thrusting the rebels and their long-running armed struggle further into the limelight.

The attack on Houthi bases came a day after the United Nations Security Council voted to condemn “in the strongest terms” at least two dozen attacks carried out by the Houthis on merchant and commercial vessels, which it said had impeded global commerce and undermined navigational freedom.

Here’s a primer on the Houthis, their relationship with Hamas and the attacks in the Red Sea.
