A "powerful" blast has been heard in the Swedish capital, Stockholm, eyewitnesses told local media. The area has been cordoned off by police who suspect the explosion was caused by a gas leak.

The blast which was described by witnesses as “powerful” occurred on Brännkyrkagatan street  at 11:40 am local time, Aftonbladet newspaper reports.

Windows were shattered in a nearby house, however, the apartment's owner told Expressen.se this is unrelated to the blast.

Stockholm police have contacted the owner of the apartment where the blast happened. “There are no signs of a crime,” the local police department said on its website.
