NEW: The Saudi-led coalition said it carried out a military operation this morning against what it described as "vital assets" used by Houthi (Houthi) forces to support military operations. The spokesman for the coalition, Turki al-Malki, said that the targets are allegedly used to support ballistic missile and UAV capabilities and to facilitate attacks that threaten Saudi Arabia, Yemen and maritime navigation in the southern Red Sea. The coalition said it would continue operations aimed at preventing Houthi (Houthi) forces from using such infrastructure for military purposes.
