Yemen’s Houthi rebels have taken control of strategic areas near the Bab al‑Mandeb Strait, a crucial link that funnels cargo from Asia to Europe.

The group insists it isn’t threatening international shipping, but it has re‑affirmed its intention to attack vessels sailing under Saudi arms.

Saudi Arabia now relies more heavily on the Red Sea route for oil exports, especially after hostilities between Israel and the U.S. pushed an alternative route via the Strait of Hormuz.

The United Nations states that at least 46,000 people have been displaced in Yemen since fighting escalated last week.
