Evening Sept. 16 local time Houthi-run Al Masirah TV released video purportedly
showing Houthis shooting down a Saudi F-15. The group earlier said it used an
improvised surface-to-air missile to strike an F-15 conducting "hostile
operations" over Marib province in northeast Yemen. Two waves of Saudi F-15s and
Typhoon jets reportedly entered Marib airspace searching for wreckage; Houthis
fired additional air-defence missiles, forcing the jets to withdraw.
