The Houthi movement Ansar Allah has urged Saudi Arabia to prepare for more extensive attacks, according to reports. Yemeni Houthis are reportedly preparing for a ground operation against Saudi Arabia and are pushing deeper into its territory. In recent weeks, the Houthis have expanded control in western Yemen, seizing the port city of Mocha and Perim Island in the Bab el-Mandeb Strait, a key maritime route connecting the Red Sea with the Gulf of Aden.
