Three students have been killed and six people wounded after a 15-year-old opened fire at his Michigan high school.
The attack happened at Oxford High School in Oxford Township, a community of about 22,000 people 30 miles (48km) north of Detroit.
The 15-year-old is in custody after being arrested at the school. Officers also recovered a semi-automatic handgun and ammunition.

The gunman’s motive remains unclear, said Oakland County Undersheriff Mike McCabe.
Officers responded at around 12:55pm local time to a flood of 911 calls about an active shooter.
Authorities did not immediately release the names of the suspect or victims but confirmed one of those injured was a teacher.
Tim Throne, the superintendent of Oxford Community Schools, said: “I’m shocked. It’s devastating.”

The school was placed on lockdown after the attack, with some children sheltering in locked classrooms while officers searched the premises.
They were later taken to a nearby shop to be picked up by their parents.
