A female student opened fire at a high school in Texas on Thursday morning, injuring another female student before killing herself.

Police were called to Alpine High School, in western Texas, 30 miles east of Marfa, at around 9am.

Female mass shooters are rare.

The Washington Post found that, of 130 perpetrators of mass shootings - killing four or more people, since August 1, 1966 - only three were female.

Ronny Dodson, sheriff of Brewster County, told ABC News that the shooter was dead, from what appeared to be self-inflicted wounds, and the shooting was over.

Another female student at the school was shot but is still alive, and an officer was reportedly shot as well in what appears to be an accidental shooting, said Mr Dodson.
