An explosion in southern Sweden on Friday left 25 people with minor injuries, according to officials.
The blast in central Linkoping rocked a pair of apartment buildings, leaving considerable damage to the structures. Officials have not determined what caused the explosion.
“As for now, we don’t have any information to believe this is terror-related," Bjorn Oberg, a police spokesman, told The Associated Press.
There were no deaths or serious injuries, police spokeswoman Asa Willsund told Reuters. The explosion occurred shortly after 7 a.m. local time, which is 3 a.m. E.T.
Police reportedly began a criminal investigation following the explosion and closed off the area surrounding the buildings. A bomb squad responded to the scene for precautionary reasons, authorities said. A number of windows and balconies in the buildings were wrecked by the blast, photos show.
Linkoping is seventh largest city in Sweden. It’s located roughly 120 miles to the southwest of Stockholm, which is the nation’s capital.
One of the buildings impacted by the blast is five stories, while the other is four.
“First I didn’t think it was anything bad, then I saw the neighbor’s window was broken so I left our apartment and saw the chaos outside,” Pontus Johansson, a 21-year-old resident of a nearby building, told Reuters of the blast.
