SANAA -- Yemen's Shiite rebels said on Monday they have "successfully" fired a ballistic missile at Riyadh for the first time, vowing more attacks on the Saudi capital.
There was no immediate comment from the kingdom but the claim came exactly a week after Saudi Arabia said a "suicide gunboat" belonging to Yemen's Iran-backed Houthi rebels rammed into one of its frigates in the Red Sea, killing two crew members.
