Which Saudi-backed target did the Houthis claim to have shot down using a surface-to-air missile in September 2026?

Explanation: The Houthis released video they said backed their claim of shooting down a Saudi F-15 fighter jet using a surface-to-air missile, following a week of intensified Royal Saudi Air Force strikes against Houthi positions. The group also claimed responsibility for strikes on Yanbu and a Saudi airbase. Such claims, even when unverified, are used by armed groups to demonstrate deterrent capability against technologically superior state air forces.
