Yemen’s Houthi rebels have launched a missile toward northern Israel, a rare target for the group as a monthlong intense U.S. airstrike campaign continues to target them.

The new US campaign of airstrikes started after the rebels threatened to begin targeting “Israeli” ships again over Israel blocking aid entering the Gaza Strip.

The Houthi rebels in Yemen have accused the United States of an airstrike on a market in Sana'a. Twelve people were reportedly killed, and another 30 injured. Washington has yet to comment on these reports.
