IS blamed for hacking TV network

PARIS — Hackers claiming allegiance to the Islamic State group simultaneously blacked out 11 channels of a French global TV network and took over its website and social media accounts Thursday in what appeared to be the most ambitious media attack so far by the extremist group.

Anti-terror prosecutors opened an investigation into the attack that began late Wednesday and blocked TV5 Monde from functioning part of the day Thursday. Operations were fully re-established Thursday evening.
