A teenager has been killed and seven others injured after two pupils allegedly opened fire in a US school.
The attack at the STEM School Highlands Ranch, near Denver, Colorado, took place on Tuesday, police said. Both attackers have now been arrested.
Highlands Ranch is just 8km (5 miles) from Columbine High School – the site of one of the US’s worst school shootings 20 years ago.
This is believed to be the 115th mass shooting in the US in 2019.
Just before 14:00 local time (20:00 GMT) the attackers “walked into the STEM school, got deep inside the school and engaged students in two separate locations”, Douglas County Sheriff Tony Spurlock said.
One suspect was a male youth, while the other was an adult man. Both were pupils at the school.
