On Oct. 4 the Saudi-led coalition said it will continue to provide full operational support to the Yemeni government and armed forces to restore state authority. Coalition spokesman Turki al-Maliki accused the Houthis of deliberate, systematic attacks on civilians and civilian infrastructure in Riyadh and other cities, and said the group attempted strikes on Mecca and Medina and on Saudi vessels in the southern Red Sea and Bab al-Mandeb. He said the coalition will take necessary measures to curb Houthi hostility, safeguard Saudi security and sovereignty, and conduct operations to remove threats to navigation in the southern Red Sea and Bab al-Mandeb, noting such threats endanger regional and international security, international trade and the global economy.
