One person has died and another has been hurt in a blast outside a metro station in a Stockholm suburb.

The blast occurred mid-morning at the Varby Gard station in Huddinge, a southern suburb of the Swedish capital. Police say a man in his 60s died after succumbing to injuries sustained when he picked up an object off the ground. The object promptly exploded. A woman aged 45 was also hurt, suffering facial injuries. Police have cordoned off the station and the square where the blast happened. A bomb squad has moved in to investigate. Local police say there is nothing to indicate the two victims were targeted, nor are there any immediate signs to suggest this was an act of terrorism.
