A powerful explosion in the southern Swedish town of Linkoping has damaged buildings and lightly injured 25 people, police said.
The cause of the explosion was unclear but police said a bomb squad was on its way to the scene in downtown Linkoping and that they had opened a criminal investigation.
"There is nothing that indicates that this incident is terror-related, we do not see that," police spokeswoman Asa Willsund said.
"We think that it occurred outside," Willsund said of the explosion. "We estimate that there are 25 people with minor injuries - no serious injuries or deaths."
Swedish public radio reported that a large blast had destroyed the windows and balconies of a five-storey residential building and damaged other neighbouring buildings.
"Many people called in about a very powerful explosion which has led to a large number of windows being blown out," police spokesman Bjorn Oberg said.
"So far we have been able to confirm that there are a number of people with light injuries. We have cordoned off a large area, several blocks."
Pontus Johansson, a 21-year-old engineer who lives in a building nearby, said he was in the shower when he heard a loud bang.
"First I didn't think it was anything bad, then I saw the neighbour's window was broken so I left our apartment and saw the chaos outside," he told Reuters.
