The Swedish Defence Research Agency reconstructed and tested the bombs and estimates that if all the bombs had worked the effect could have been similar to the Boston Marathon bombing in 2013, where three people died and over a hundred people were injured.
FOI rekonstruerade och provsprängde bomberna och uppskattar att om samtliga bomber hade fungerat så hade de kunnat få en liknande effekt som bombdåden vid Boston Marathon 2013, där tre personer dog och över hundra personer skadades.
