Are Houthi attacks now reaching Saudi Arabia's cities?

The Houthis fired ballistic missiles at Aden, aiming at its airport and presidential palace, a Yemeni military statement said. It did not say whether anyone was hurt or whether the missiles hit.

Saudi coalition spokesman Turki al-Malki says air defences downed a drone over Riyadh and another over Medina, home to Islam's second holiest site. Those are his claims, and the coalition is the only source.

Earlier strikes on Riyadh's airport were deadly, and one report says they shut it for two weeks.

The coalition has repeatedly accused the Houthis of targeting Mecca and Medina, charges the Houthis deny. So strikes have reached Riyadh itself, but the claims over Mecca and Medina remain disputed.
