Houthis say they targeted Saudi capital with ballistic missiles

Iran-backed Houthi militants in Yemen say they carried out drone and ballistic missile attacks on the Saudi capital Riyadh, as well as energy sites on the country's Red Sea coast.

Saudi authorities said they intercepted and destroyed a ballistic missile fired at Riyadh earlier that day, without confirming any further strikes or causalities.

Earlier, a column of black smoke was seen rising from fuel tanks near the Saudi capital's international airport, where flights were disrupted temporarily on Saturday.

Air raid alerts had sounded in the capital for the first time since the Iran-backed Houthis increased their attacks on Saudi Arabia in July.

Air defences also stopped "hostile attempts to target civilians" in the cities of Bish, Taif, Farasan and Yanbu, an official spokesperson for the Saudi-led coalition said in a statement.

In a statement posted online, Houthi military spokesman Yahya al-Sarea said a "large number of ballistic and cruise missiles and drones" had been used to attack "sensitive sites" in Riyadh and Aramco state oil and gas company facilities in Yanbu on the coast.

He added that the attacks were "in response to the Saudi enemy's criminal attempts" to target the Yemeni capital Sanaa.

Earlier, Sarea had accused Saudi Arabia of carrying out 300 strikes across Yemen during the past week.
