Police say two men have died after a hand grenade apparently exploded in their car in the Austrian capital.
Officers found the men in a Bulgarian-registered car in Vienna's Ottakring district early Saturday after a passer-by reported hearing shots or an explosion. One man in the car was already dead and the other died at the scene.
Police were working to identify the men, believed to be around 50, and piece together what happened.
The Austria Press Agency reported that evidence points to a hand grenade having exploded and quoted police spokesman Thomas Keiblinger as saying officials "have no indications that it was thrown into the car." No other weapons were found.
