Moments after the alleged terrorist attack in Las Ramblas, Barcelona, Spanish police reportedly got in a shootout with a group of men in the coastal resort town of Cambrils, located about 118 kilometers south-east of Barcelona.
In the shootout, the police killed four men, and wounded one. It is not clear whether the men were involved in the Barcelona attack, or if they were gearing up for a different attack, but according to the commentary by the cameraman of the aftermath video, the killed men wore belts with the explosives.
Props to Best Gore member @ElBosnio for the video. It was filmed from a distance so it leaves a lot to be desired, but it does appear to show three out of four casualties:
