A school is in mourning for three teenagers who died after the car they were in crashed into a wall.

Jenna Barbour, 18, Josh James-Stewart, 15, and David Armstrong, 16, who were named locally, died of their injuries following the incident on a minor road in East Lothian last night.

Another passenger in the car, a 16-year-old boy, is being treated at Edinburgh's Royal Infirmary for serious injuries.

The crash happened on an unclassified road in Tyninghame at about 8.25pm when the Peugeot 206 they were travelling in hit a wall. The three died at the scene. No other vehicles were involved, Police Scotland said.

The three boys involved are pupils at Dunbar Grammar and Ms Barbour is a former pupil of the school.

A special assembly was held at the school today and mourning pupils were allowed to leave early.

East Lothian Council's education and children's well-being spokeswoman Shamin Akhtar said: "Dunbar Grammar School is mourning the loss of three students killed in a road accident near East Linton last night.

"Dunbar is a very close and strong community, and very few young people at school will not have known at least one of the young people involved.

"A special assembly was held this morning with S5/S6 to reflect on what had happened and to offer comfort and support. Teachers across the school are supporting young people and counselling services are also on hand.

"Students have been offered the opportunity to go home as long as there's someone there to support them. However, many have opted to stay to seek support from their friends and staff.

"The grief will be felt for a long time and at the moment the school is focusing on supporting its young people and the families of those who died, and on sending our best wishes and thoughts for the recovery of the young person who survived the accident."

Road policing officers are investigating and asked anyone who can help with their inquiries to contact them.

A Police Scotland spokesman said: "Tragically, this incident has resulted in three young people losing their lives and we are currently trying to establish exactly what has happened.

"Any motorists who were on the road at the time and have information that can help with our investigation is asked to contact police immediately."
