Two teenage girls in the US state of Texas have been arrested for plotting a “mass casualty attack” with pipe bombs and guns, police say.
The girls, ages 15 and 16, were planning an attack at Memorial High School in a suburb of Houston, police told KHOU, an affiliate of the BBC’s US partner CBS News.
The plot – which was shared on social media – was detailed enough that officials deemed it to be credible, CBS reported.
