Schools across the US are on alert amid the rise of a disturbing TikTok trend threatening violence against campus communities.
Students and parents have been asked to report alarming posts to law enforcement and not to share them further in a bid to keep them from going viral.
The anonymous social media threat has suggested that school shootings and bombings could take place on Friday 17 December in schools across the country.
The posts, which ABC2 said are believed to have originated in Arizona, encourage students to stay home that day.
Several school districts and police departments across the country have responded by releasing statements assuring communities that no credible threats have been identified.
The threat comes just over two weeks after the US was rocked by its worst school shooting since 2018.
