Houthis claim major advance in Yemen and tighten grip on Red Sea shipping lane

What Happened

Houthi forces claimed a major advance on Yemen's western Red Sea coast, consolidating control over the Bab al-Mandab Strait. A source from Yemen's internationally-recognised government told the BBC that the Iran-backed group seized Perim Island at the mouth of the waterway on Friday, one day after capturing the strategic port city of Mokha from Saudi-backed pro-government forces, according to military sources. A Yemeni military official told AFP that the Houthis now control the entire coastline. Houthi military spokesman Yahya Sarea said a 'large-scale' military operation was launched on 3 September in response to Saudi Arabia's 'blatant aggression', but the statement did not mention Perim Island. The Houthis said maritime navigation is safe for all companies except Saudi vessels; Saudi Arabia has not publicly commented.

Why It Matters

The Houthis' consolidation of the western Red Sea coast and Perim Island places them astride the Bab al-Mandab Strait, a chokepoint through which Saudi Arabia ships oil to Asian customers and which has grown more important amid the effective closure of the Strait of Hormuz in the US-Iran conflict. This Iranian-backed advance threatens to disrupt global energy transit, already contributing to a surge in oil prices, and escalates the collapsed truce between the Houthis, Yemen's government and Saudi Arabia.

Watch For

Watch for whether Saudi Arabia or its coalition responds publicly or militarily to the fall of Perim Island and Mokha, any Houthi attacks on Saudi vessels or oil infrastructure, and further advances along the coastline. Monitor IOM displacement updates, as it said numbers were rising by the hour, and oil market reactions to any threat to Bab al-Mandab shipping.
