Houthi-run Al Masirah television, meanwhile, reported that Saudi Arabia had carried out an attack on Sanaa, although Riyadh had not immediately confirmed the claim.Yemen’s armed forces said early on Sunday that they were conducting strikes against Iran-aligned Houthi forces in the capital Sanaa and the Houthi stronghold of Saada.The latest strikes mark a renewed escalation between the Saudi-backed Yemeni government and the Houthis.

Reuters reported that Riyadh is considering an offensive aimed at reversing recent Houthi gains along Yemen’s Red Sea coast and regaining control of the strategic Bab el-Mandeb strait.The planned operation would be led on the ground by Yemeni forces overseen by Saudi Arabia and supported by Saudi airstrikes. According to six regional and Western officials cited by Reuters, more than 100,000 Yemeni troops could be mobilised, depending on the scale of the offensive.Saudi officials are considering either a narrowly focused assault around Bab el-Mandeb or a broader, multi-front campaign involving coordinated attacks in Al-Bayda, Marib, Taiz and Al-Jawf. Reuters reported that the timing remains uncertain, with estimates ranging from within weeks to after the US midterm elections in November.
