Meta CEO Mark Zuckerberg has apologised to families who say their children have been harmed by social media, during a fiery hearing in the US Senate. Mr Zuckerberg – who runs Instagram and Facebook – said “no one should go through” what they had. He was questioned along with the bosses of TikTok, Snap, X and Discord for almost four hours by senators from both parties. Lawmakers wanted to know what they are doing to protect children online.
