Yemen's internationally recognised government announced Monday it had recaptured the Dhubab district and seized positions near the Bab al-Mandeb strait, one of the world's most critical maritime chokepoints. The operation, conducted by the Homeland Shield Forces and Giants Brigades with air cover from 100 Saudi-led coalition fighter jets, reportedly cut Houthi supply lines to the strait. A separate "strategic offensive" on Sanaa was announced shortly after. Al Jazeera could not independently verify any battlefield claims. The timing is not coincidental. Pakistani Deputy Prime Minister Ishaq Dar arrived in Riyadh the same day for the first operational meeting under the Mecca Joint Defence Agreement, signed August 7, 2026, by Saudi Arabia, Turkiye, and Pakistan. That pact contains a mutual-defence clause — an attack on one signatory is treated as an attack on all three. Pakistan's defence minister and military chief are at the table alongside their Saudi and Turkish counterparts. The military context matters. In mid-September, Houthis swept across western Yemen, seizing the port city of Mocha and strategic islands in the Bab al-Mandeb. Anti-Houthi forces stabilised the lines but could not reverse the gains — until now. The Dhubab operation represents the first significant territorial rollback since the Houthi autumn advance, though the durability of these gains remains entirely unverified. Pakistan's Dar disclosed last week that the Riyadh talks would also address a proposal for political engagement with the Houthis, relayed through Tehran. This dual-track approach — military pressure plus a diplomatic off-ramp — mirrors the classic escalate-to-negotiate playbook. Whether Iran-aligned Houthis would accept terms while losing ground is the central question nobody can yet answer. The humanitarian cost is accumulating with each phase of the war. Since the Houthis seized Sanaa in 2014, Yemen has been fractured. A 2022 truce collapsed in July, and the current escalation leaves tens of thousands facing continued displacement and hunger. Al Jazeera's Michael Appel noted that civilians remain caught between fragmented front lines with no clear path to safety. The Mecca pact transforms the strategic equation. Saudi Arabia now has a formal trilateral framework to sustain operations — Turkiye brings drone and defence-industry capability, Pakistan brings a nuclear-armed military with regional expeditionary experience. The question is whether this pact functions as a genuine deterrent architecture or merely a diplomatic signal wrapped in a mutual-defence clause that nobody intends to invoke. Control of Bab al-Mandeb is the prize that makes this more than a local war. Roughly 10% of global trade passes through the strait. Every day it remains contested is a day global shipping routes carry additional risk premiums. The government's ability to hold Dhubab — not just take it — will determine whether the strait returns to anything resembling stable passage.
