UPDATE: Probably not terrorism. Dutch reports (source: http://www.nu.nl/buitenland/2692446/live-aanslag-luik.html http://www.nu.nl/buitenland/2692446/live-aanslag-luik.html ) are said to indicate two men had escaped from the main Courtroom (located on the square where the shooting/attack took place).
