Social media giants on Friday hit out at a landmark Australian law banning them from signing up under-16s, describing it as a rush job littered with "many unanswered questions." The UN children's charity UNICEF Australia warned the law was no "silver bullet" against online harm and could push kids into "covert and unregulated" spaces online.

Australia’s House of Representatives passed a bill to ban children younger than 16 years old from social media. If it passes, the law would be a world first.

A social media ban for children under 16 passed the Australian Senate Thursday and will soon become a world-first law.
