Iran has unveiled a 'secret' underground naval base that gives the country the ability to protect itself from "enemies big and small", with footage of the facility shared across state broadcast channe

Footage claiming to show a secret Iranian underground naval base was made public by Tehran’s state television on Saturday - the second video the Islamic Republic has released of its arsenal ahead of US President-elect Donald Trump's inauguration.

An Italian journalist detained in Iran whose fate became intertwined with that of an Iranian engineer wanted by the United States said she assumed she would have been held much longer and said her boyfriend's contact with Elon Musk might have been "fundamental" to her release.
