Several cars and houses were burned on Wednesday night in southern Swedish municipality of Kristianstad, the Swedish Television SVT reported on Thursday.

A total of seven cars burned in different locations throughout the city. Even though the locations are far from each other, according to the police, it is possible that the car fires were arson attacks.

Earlier the same night, police and rescue services received alarms of a couple of houses caught fire. Among the burned houses were a pizzeria and a garage building that were completely destroyed.

"The fires happened on residential area, but no one got hurt," chief police officer Tommy Bengtsson told SVT.

According to the local newspaper Kristianstadsbladet, several fire units were on the spot trying to prevent the fire from spreading to close by houses.

For now, it is unclear what caused the fires or whether there is a connection between them.
