Yemeni Houthis' agency Saba, controlled by the rebels, has announced the launch of the Burkan H-2 ballistic missile launch toward Riyadh airport.
The missile has allegedly reached its target. Saudi Arabian officials have yet to comment on the information.
The alleged attack comes just 10 days after the Saudi military intercepted a Houthi missile fired from Yemen, targeting civilian areas of the southwestern Saudi province of Najran on January 20.
The Houthis have repeatedly targeted areas in Saudi Arabia with missiles, with the Riyadh airport being targeted on November 4, 2017, prompting the Arab coalition to impose a temporary blockade on Yemeni ports.
The military conflict dates back to 2015, when the fight between the government of President Abd Rabbuh Mansur Hadi and the Houthi rebels, backed by Saleh army units, broke out. The Saudi-led coalition of mostly Persian Gulf Arab countries has interfered in the conflict since March 2015 upon Hadi's request, carrying out airstrikes against the Houthis.
