A gunman who shot and injured two teenage students at a high school in the US state of Maryland has died of a gunshot wound, police say.
A 16-year-old girl, who is in a critical condition, and a 14-year-old boy are being treated in hospital.
The attack happened on Tuesday morning before lessons at Great Mills High School in St Mary’s County, 65 miles (104km) south-east of Washington DC.
It comes a month after a high school shooter killed 17 in Parkland, Florida.
An armed campus guard exchanged gunfire with the attacker – who has not been identified – but it is unclear if the gunman was hit by the guard’s gunfire or shot himself.
