Paris, April 9 (IANS): The French television network 'TV5Monde' said it suffered an attack from hackers from the Islamic State (IS) terror group, media reported on Thursday.

TV5Monde said its TV station, web site and social media accounts were all hit, BBC reported.

The hackers also posted documents purporting to be ID cards of relatives of French soldiers involved in anti-IS operations.

TV5Monde regained control over most of its sites about two hours after the attack began late on Wednesday night.

Its digital director, Helene Zemmour, called the hack "unprecedented and large-scale".

A message posted by the hackers on TV5Monde's Facebook site read: "The CyberCaliphate continues its cyberjihad against the enemies of Islamic State."

They replaced TV5Monde's social media profile pictures with a masked Islamist fighter.

France is part of the US-led coalition carrying out air strikes against IS in Iraq and Syria.

In January, the Twitter and YouTube accounts of the US military command were hit by pro-IS hackers. But Centcom said it was "cyber-vandalism" and not a serious data breach.
