A young man from Limavady has died and a second man is fighting for his life following a collision between a car and a lorry on a mountain road.
The crash took place between a Peugeot 306 and a Volvo lorry on the Broad Road between Limavady and Coleraine at 2.20pm on Tuesday.
The road remained closed for most of the day, while police investigated the accident.
The deceased was named locally last night as Kyle Simmons, a student at the college in Limavady.
The passenger in the car was taken to the Altnagelvin Hospital following the crash. He remained in a serious condition last night.
The two men are believed to be in their early 20s.
Limavady Mayor Gerry Mullan said people in the area were "very, very distressed" by the accident.
"The community is shocked at such a serious incident in their midst," he said. "Particularly involving such young people.
"It is very, very distressing for the people of this area."
Mr Mullan said his thoughts and prayers were with the family of the young man who had died and also with the second man who was being treated in hospital.
"This shocking accident really brings home the danger on the roads to you," he said.
The PSNI have urged anyone who witnessed the road traffic incident or who was travelling in the area at the time to contact Limavady Police Station.
Eleven people have been killed on Northern Ireland roads already this year.
