A support group of the ISIS has released a video that threatened to take down Facebook and Twitter heads, Mark Zuckerberg and Jack Dorsey for deletion of accounts. The images of the CEOs, which were marked with bullet holes or engulfed in flames, featured several times in the 25-minute video.

The video has been created by a group of ISIS supporters who call themselves the “Sons Caliphate Army”. The video is a response to the deactivation of the ISIS related accounts from both the social media platforms, the Fox 6 Now reported.

Towards the end of the video, titled “Flames of the Supporters,” a message in English for Zuckerberg and Dorsey read, “To Mark and Jack, founders of Twitter and Facebook / and to their Crusader government / You announce daily that you suspended many of our accounts / And to you we say: Is that all you can do? You are not in our league. If you close one account we will take 10 in return and soon your names will be erased after we delete you [sic] sites, Allah willing, and will know that we say is true. [sic]”

The video also showed the group hacking into Facebook and Twitter accounts and posting ISIS propaganda after changing the profile pictures. According to the group, they have hacked more than 10,000 Facebook accounts, more than 5,000 Twitter accounts and more than 150 Facebook groups.

This month, Twitter confirmed that it deactivated more than 125,000 accounts for supporting and promoting terrorist acts, the Mirror reported.

“Like most people around the world, we are horrified by the atrocities perpetrated by extremist groups,” a spokesperson for Twitter said. “We condemn the use of Twitter to promote terrorism.”

The ISIS is known to utilize the social media to reach out to supporters and spread radicalism. They have also been using the platforms to lure new recruits.
