STOCKHOLM, Jan. 12 (Xinhua) -- Six people died in a head-on collision in Sweden on Saturday, according to Swedish newspaper Aftonbladet.

The accident occurred on curving roads near the northern city of Kiruna when a freight truck crossed on the wrong side of the road, into the path of a minibus carrying seven people.

Emergency services were called to the scene at 01:56am, where they found the minibus in a ditch off county road 395 between Vittangi and Pajala.

Six of the seven people travelling in the minibus were killed. The seventh was airlifted to hospital by helicopter with moderate injuries. Although police have not yet confirmed the identities of the victims, Aftonbladet reported that they were foreign citizens.

Mining company Kaunis Iron, which owns the truck, published a press release saying that the driver of the truck was unharmed but severely shaken. The driver has been questioned by police.

Police spokesperson Liv Fahlen said the investigation is ongoing and further information will be released later on Saturday.
