Zuckerberg: Facebook is 'in an arms race with Russia'

Facebook CEO Mark Zuckerberg has told US senators his company is in a constant battle with Russian operators seeking to exploit the social network.

"This is an arms race. They're going to keep getting better," he said, according to BBC News.

Mr Zuckerberg was answering questions in the wake of the Cambridge Analytica data collection scandal.

He also revealed Robert Mueller, the special counsel investigating alleged Russian meddling in the 2016 election, had interviewed Facebook staff.

Mr Zuckerberg said he has not been among those interviewed by Mr Mueller's office.

But he added: "Our work with the special counsel is confidential and I want to make sure that in an open session I'm not revealing something that's confidential."

In February, Mr Mueller's office charged 13 Russians with interference in the 2016 election, along with three Russian companies.


One was the Internet Research Agency, sometimes referred to as a "Russian troll farm", which the indictment said had a "strategic goal to sow discord in the US political system".

Mr Zuckerberg said the company was now developing new tools to identify fake accounts.
