ISIS has made threats to Facebook CEO Mark Zuckerburg and Twitter CEO Jack Dorsey in a new video showing their photos with digitally added bullet holes.  

The Mirror reports that with this new video, the extremist hackers claim to be fighting back against efforts made by the social media companies to wipe their platforms clean of terrorist content. 

The video shows that the terrorists claimed to have hacked more than 10,000 Facebook accounts, more than 150 Facebook groups and over 5000 Twitter profiles. 

A slide toward the end of the video reads, in English: "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, #Sons_Caliphate_Army". 

Twitter has confirmed it suspended over 125K accounts for promoting or threatening terrorist acts this month. A spokesman for Twitter said, “We condemn the use of Twitter to promote terrorism.”

Facebook's COO, Sheryl Sandberg, discussed pushing for an aggressive response to ISIS to help fight terrorism online. “The best thing to speak against recruitment by ISIS are the voices of people who were recruited by ISIS, understand what the true experience is, have escaped and have come back to tell the truth. Counter-speech to the speech that is perpetuating hate we think by far is the best answer.”

The video comes after Facebook, Twitter and Google were advised to help ramp up Britain's fight against terrorism earlier this month to remove jihadist posts.
