The Houthis claimed in September 2026 to have shot down which Saudi aircraft using a surface-to-air missile?

The group also claimed strikes on Yanbu and a Saudi airbase. For CSS International Relations, the episode demonstrates how relatively low-cost air defence systems in the hands of non-state actors can impose significant costs on technologically superior air forces.
