Dramatic aerial footage reportedly shows the moment two US-made truck-mounted quad-launchers for the Patriot surface-to-air missile systems are destroyed.

A giant explosion followed a strike by a Russian hypersonic Iskander missile.

The Russians have called it the first video-confirmed destruction of the Patriot complex displayed by Ukraine. Each system is believed to cost $400million, while missiles can cost up to $6million each. 

The hit comes after Ukraine is believed to have deployed the Patriot to down a succession of Russian war planes in recent weeks.
