An explosion has badly damaged part of a building that housed a Turkish cultural association in a Stockholm suburb, but no one was injured in the blast.

All the windows of the centre were blown out and technicians were on site to investigate the cause of the blast.

"No one was inside. No one was injured. It had been locked since earlier in the evening," a police spokesman said.

No one has been arrested and there are currently no suspects, he added.

Earlier on Wednesday, 28 people were killed and dozens wounded in Turkey's capital Ankara when a car laden with explosives detonated next to military buses near the armed forces' headquarters, parliament and other government buildings.
