(Reuters) - Facebook Inc said on Tuesday it has invested more than $13 billion in safety and security measures since 2016, days after a newspaper reported the company had failed to fix "the platform's ill effects" researchers had identified.

The social media giant said it now has 40,000 people working on safety and security, compared with 10,000 five years ago.
