The collision occurred around 6:30 a.m. near Hillerød, about 40 kilometers (25 miles) north of Copenhagen. Roughly a dozen other people have minor injuries, according to the Greater Copenhagen Fire Department.

There were 38 people aboard the two trains, according to a spokesperson for the North Zealand police.
