The European Union is set to ban social media for children under 13 and allow only limited, supervised access until age 15, EU chief Ursula von der Leyen said Wednesday.

"No social media under the age of 13. No personal account under the age of 15," she said during her annual address to the European Parliament.

"That means, from 13 until a child turns 15, only mini accounts set up and supervised by parents, with limited features and time restriction," she added.
