The Saudi -led coalition fighting the Iranian-backed Houthi rebels said Thursday it has thwarted a missile attack on the holy city of Medina as well as another attack in the eastern part of the kingdom.

Missiles and drones have been intercepted over Riyadh after the Saudi-led coalition fighting in Yemen struck a fuel depot near the Houthi-controlled capital, Sanaa, its spokesperson says.

Two senior Iranian officials told Reuters that Tehran changed its maritime tactics approximately 10 days ago, increasing attacks on vessels it considers in violation of its restrictions. Operations have expanded beyond Hormuz into the Gulf of Oman and waters near Qatar and the United Arab Emirates.

Iran has begun rebuilding missile-production sites targeted by Israel during its 12-day war in June, satellite images analyzed by The Associated Press show, but a key component is likely still missing — the large mixers needed to produce solid fuel for the weapons.

Yemen's information minister says the prime minister and other ministers were unhurt when ballistic missiles hit al-Maashiq Palace.
