Security is being tightened around Facebook co-founder, Mark Zuckerberg, with 16 guards at his California home.  This is in a bid to ensure his safety.

The development has led to his annual security allowance being increased to $10 million.  The company said in a filing to US regulators that it is due to threats ''arising directly as a result of his position as Facebook’s founder, chairman and CEO.''



The increased allowance is to pay for even more bodyguards, improved security at Mr Zuckerberg’s homes and the use of private aircraft. This is in response to an Isis series of images featuring Mr Zuckerberg in an orange jumpsuit and his severed head, with the message “Go to hell, Mark.”

It is believed that Isis is targeting Facebook to retaliate against its measures to censor pro-Isis content and groups, and because Facebook is seen as a western symbol.

There are also claims that Zuckerberg received regular threats from disgruntled Facebook users, including threats to his family.



2018 is a year the Facebook co-founder will not forget in a hurry, with a group of investors also seeking to oust him from his position as chairman, believing he is an increasing liability to the company.
