AN Iranian propaganda video shows a US naval fleet being sunk with a giant tidal wave.

The disturbing footage, which also features the burning of an American flag, includes the caption “I will break your legs into pieces.”

Titled 'Steadfastness 2', the professional looking clip was produced by an office of the country's supreme leader Ali Khamenei, according to Middle East Media Research Center (MEMRI).

Similar to the propaganda released by terror group ISIS, the two-and-a-half-minute video starts with a group of boys playing football on a beach.

However the tone soon darkens, when a plane is gunned down by a fleet of American warships.

The video then shows a group of Iranian men wielding their national flag while singing and advancing towards the shore.

The force of the mens' anger and patriotism creates tidal wave which overwhelms the Naval fleet and even takes out helicopters in the sky.

The caption before the deadly tidal wave reads: “If you step over me, I will break your legs into pieces.”

Last week, footage emerged of four Iranian vessels conducting a “high speed intercept” of American warship USS Nitze near the Persian Gulf.

The US has a huge naval base in Bahrain and their presence in the region is a source of tension between Washington and Iran.

The latest video seems to be inspired by a 1988 incident involving Iran Air Flight 655 which was accidentally shot down by the US military killing 290 people.
