Hacking group Anonymous has claimed responsibility for taking down 800 Twitter accounts, 12 Facebook pages and over 50 email addresses as they were linked to Islamic State (IS) terrorist group.
According to CNN, Facebook said that it had shut down 11 out of 12 pages listed by Anonymous because they breached its rules.
However, Twitter has not yet commented on the issue.
Facebook declined to comment on whether the company was alerted by the hackers about the offending content.
Last month, Anonymous group had declared war against Islamic extremists and said in a YouTube video that they would take down all their websites and social media networks.
