Saudi air defences intercepted and destroyed a Houthi ballistic missile aimed at the kingdom's southern region, the Saudi-led coalition in Yemen said on Monday, as fighting continued along several fronts between the Iran-aligned Houthi movement and forces loyal to Yemen's internationally recognised government.

Coalition spokesman Major General Turki al-Maliki said in a statement on Monday that the defences had intercepted and destroyed the missile before it could reach its target. He had earlier said that air defences destroyed a drone launched towards the southern region on Sunday evening.

Also on Monday, the Saudi Civil Defence authority issued and then lifted alerts warning of potential danger in the city of Abha and the provinces of Khamis Mushait, Taif and Najran. The authority warned residents against filming, publishing or sharing information related to missile and drone attacks.

The interception followed a weekend in which the coalition said its air defences had destroyed two ballistic missiles launched towards Riyadh and two cruise missiles over Riyadh and the southern region on Sunday, as well as a ballistic missile aimed at the Eastern Province earlier that day.

Inside Yemen, Houthi-affiliated media reported that seven people were wounded in Saudi-led coalition air strikes on the Red Sea port city of Hodeidah. Four people were wounded in attacks on the Ras Isa port dock, while three others were injured in a strike on an oil company site in the governorate's Bajil district, the reports said. There was no comment from the Saudi-led coalition on those reports.

Yemeni army spokesman Colonel Majed Abdullah al-Nazili said on Sunday evening that government forces had conducted 1,272 targeting operations against Houthi fighters, fortifications and weapons supplies over 24 hours. He said operations were continuing in al-Jawf, neighbouring Marib and al-Bayda to the south, and claimed government forces had killed roughly 500 Houthi fighters and destroyed or disabled nearly 170 vehicles and pieces of heavy weaponry. Those claims could not be independently verified.

The fighting is part of Operation Dawn of Yemen, the campaign launched last month by Yemen's internationally recognised government to regain territory held by the Houthis, who seized the capital, Sanaa, in 2014. Full-scale fighting reignited in Yemen in September, when the Houthis made gains that tightened their grip on the Red Sea coast.

The conflict is also deepening the humanitarian crisis in the south-western city of Taiz, where the Houthis continue to besiege the city and block the entry of food, fuel and medical supplies. Taiz Governor Nabil Shamsan has called for urgent help for the city's deteriorating health facilities, saying 120 health centres have stopped operating and another 66 are close to shutting down since the Houthis cut off supply routes to the city in early October. At least 23 trucks were damaged or overturned in the past two weeks while seeking alternative routes to Taiz. The city is Yemen's third-largest and home to about one million of the country's roughly 43 million people.
