COPENHAGEN, Denmark (AP) — Two trains collided in Denmark early Thursday, prompting a massive emergency response for what police called a major accident.

The collision occurred around 6:30 a.m. near Hillerød, about 40 kilometers (25 miles) north of Copenhagen.

Everyone has been evacuated out of the trains, according to a spokesperson for the North Zealand police. Officials would not comment on the number of injured people or the seriousness of the injuries.

Photos from the scene show the front ends of the trains smashed, though both remained upright on the tracks.

The mayor of the nearby town of Gribskov, Trine Egetved, in a post on Facebook, said some of the injured were flown to the hospital.

She said the crash occurred on a local rail line that's used by many Gribskov residents, employees and schoolchildren.

No other details were available.
