Summary

The Houthi rebels, backed by Iran, have taken control of the Red Sea coastline in Yemen, including the strategic island of Perim, which is located in the Bab el-Mandeb Strait. The capture of these areas has raised concerns about a return to all-out war in Yemen and poses a threat to global oil supplies. If the Houthis can successfully threaten shipping along this key waterway, it could lead to reduced oil exports through another major route, exacerbating the world's energy crisis. Oil prices have already risen above $100 per barrel for the first time since May, amidst these developments.

Story summary

Houthis captured the Red Sea port city of Mokha, near Bab al-Mandeb Strait, on September 10-11, 2024, after a week-long offensive. The seizure intensified fighting along Yemen’s western coast, with government forces retaliating by launching airstrikes and artillery strikes against Houthi positions. Government spokesperson Majed Abdullah al-Nazili confirmed the Houthis' control over Mokha and surrounding areas, including key roads. This move gives the Houthis strategic leverage over a crucial shipping route that handles about 25% of daily petroleum shipments worldwide. The capture also threatens to isolate Gulf oil-producing countries from their main shipping routes through Bab al-Mandeb Strait, similar to Iran's closure of the Strait of Hormuz. Yemen’s internationally recognized government is struggling to counter this advance, with civilians in Mokha fleeing to Aden for safety.
