The Houthi-run Saba News in Yemen said the missile had been a Burkan H2.
The rebel group is believed to have access to a stockpile of Scud ballistic missiles and home-grown variants. Saudi forces have previously brought them down with Patriot surface-to-air missiles bought from the US.
In May, a day before President Donald Trump was due to arrive in Riyadh for a visit, the Houthis fired a missile towards the city, but it was shot down 120 miles from the capital.
Yemen has been devastated by a war between forces loyal to the internationally recognized government of President Abdrabbuh Mansour Hadi and those allied to the Houthi rebel movement.
Saudi Arabia is leading a campaign to defeat the Houthis, and is the biggest power in an international air coalition that has bombed the rebel group since 2015.
On November 1, a suspected strike by the Saudi-led coalition killed at least 26 people at a hotel and market in northern Yemen, medics and local officials said.
The coalition, which rights groups say has bombed schools, hospitals, markets and residential areas, said it struck a “legitimate military target”.
Late King Abdullah of Saudi Arabia was buried on January 23 in an unmarked grave in a public cemetery in Riyadh.
Leaders of the Muslim world and thousands of Saudi subjects paid their final respects to King Abdullah at a simple ceremony at a Riyadh mosque after Friday prayer.
In accordance with royal custom, the body of King Abdullah, who died at 1 AM., was swathed in white and laid out for visitation at the Imam Turki ibn Abdullah Grand Mosque in the capital.
The afternoon funeral was attended by Middle East monarchs and a few presidents from countries near enough to Saudi Arabia to travel to the ceremonies that by Islamic practice must be conducted before the next sundown following a believer’s death.
World leaders who plan to attend memorials scheduled this weekend sent condolences and praise for King Abdullah’s role as a mediator between the West and Islam.
Jordan’s King Abdullah II left the World Economic Forum in Davos, Switzerland, to attend the funeral and declared 40 days of mourning in his own kingdom.
Palestinian Authority President Mahmoud Abbas declared “much sadness” at the news of King Abdullah’s passing and announced three days of mourning in the Palestinian territories.
Turkish President Recep Tayyip Erdogan praised King Abdullah for “strengthening cooperation and solidarity in the Muslim world, especially concerning the Palestinian question and the situation in Syria.”
Iran, Saudi Arabia’s chief rival in the Muslim world, sent condolences to the Saudi people and said Foreign Minister Mohammad Javad Zarif would travel to Riyadh to pay respects.
Saudi Arabia’s more austere form of Islam eschews public displays of grief and elaborate ritual, even for its monarchs, who are among the world’s richest men.
King Abdullah was reported to have a net worth of $20 billion.
The funeral was open to the public, including women in their separate section of the mosque, and shops and businesses will remain open during a three-day mourning period.
