A man has been shot dead in Orly Airport in Paris after grabbing a gun from an anti-terror officer. 

The man was a radicalised Muslim and was known to French intelligence services, according to a police source.

The attacker took the female officer's weapon before seeking refuge in a store. 

The airport has been evacuated, and flights are being diverted to Paris' other airport, Charles de Gaulle.

"We were sitting in Hall Three when all of a sudden people started running and telling us to run with them," Ellie Guttetter, 18, from the US told the BBC.

"The people running were passengers and flight attendants. It was pretty chaotic and everyone was panicking – it was scary."
