A hacking group associated with the Islamic State militant group has issued an apparent threat against Facebook founder Mark Zuckerberg and Twitter founder Jack Dorsey.
The “Sons of the Caliphate” posted a 25-minute video called “Flames of the Supporters” which shows the two tech titans engulfed in flames with bullet holes.
The video boasts that IS members still have accounts on Facebook and Twitter despite steps being taken to banish them.
In the video they claim 10,000 Facebook accounts, 150 Facebook groups and over 5,000 Twitter accounts.
"You announce daily that you suspend many of our accounts, and to you we say: Is that all you can do? You are not in our league," text on the video clip reads, according to Vocativ, which first reported on the video. "If you close one account we will take 10 in return and soon your names will be erased after we delete your sites, Allah willing, and will know that we say is true."
Facebook and Twitter have both taken measures to remove content posted by IS supporters.
Twitter, which says it has over 320 million active users said it has suspended more than 125,000 accounts related to IS since mid-2015.
Facebook removed the profile of San Bernardino shooter Tashfeen Malik for violating terms of service. The company says it forbids content that praises or promotes “acts of terror.”
The companies increased their vigilance regarding IS-related content after a summit with federal law enforcement officials in the wake of the terror attacks in Paris and San Bernardino.
Social media has been an effective way for IS to spread its message and to recruit new members.
Neither Twitter nor Facebook have commented on the video.
