The shooting that killed four people at the Jewish Museum of Belgium in Brussels last weekend was likely a terrorist attack, said Wenke Roggen, a spokesperson for the Belgian Federal Prosecutor’s Office. A 30-second video released by police shows a man taking a rifle out of a bag and shooting into a room before promptly leaving the scene. “The analysis of the first images seems cold-blooded and apparently determined,” Roggen said Monday at a press conference. “It took less than 90 seconds. This combined with the fact that the shots were fired inside the Jewish museum makes us believe that the crimes were committed with a terrorist motive.”
