The Iranian Revolutionary Guard has announced it has downed an American unmanned plane that entered Iran's airspace.

According to the statement, the drone is a ScanEagle and has made a number of reconoissance flights over the Persian Gulf in the end of November.

According to Iranian sources, the plane, probably launched from a large battleship in the gulf, hade encroached upon Iran's airspace.

In response, the US Navy has said that they are checking the information, but have no records of a drone missing.

The US Navy also added that the drone mission that the Revolutionary Guard probably refers to had been conducted in international airspace.
