The Iran-aligned Houthi movement launched missiles on the Saudi capital Riyadh on Sunday, and reinforced Yemen's main port city of Hodeida as an Arab coalition moved closer to the city center in the largest offensive of the war.

Saudi Arabia's air defense forces intercepted two ballistic missiles over Riyadh, state media reported, in at least the sixth attack targeting the Saudi capital since December. Houthi-run media said the rockets were aimed at the Saudi defense ministry and other targets.

The Saudi-led military alliance launched its assault on the heavily defended Yemeni Red Sea city of Hodeida on June 12 to try to weaken the Houthis by cutting off a key supply line for the group, which controls the Yemeni capital Sanaa and most populated areas.
