The U.S. Navy confiscated weapons bound from Iran to Houthi rebels in Yemen for at least the third time in two months on March 28.  U.S. forces aboard the USS Sirocco seized a cache of weapons from a small boat in the Arabian Sea.  The weapons included about 1,500 Kalashnikov rifles, 200 rocket-propelled grenade launchers, and 21 .50-caliber machine guns.
