An explosive noise bomb exploded in hours of this night (3/20/11) against the Chilean-North American Institute in Viña del Mar, located on Calle 2 Oriente 385.
The device caused a loud noise and smoke emission, but so far it is unknown whether caused other damage.
The information was transmitted to the radio for many users on Twitter, who reported that both police and fire departments were already responding.
Meanwhile, neighbors who came and saw what happened, returned to their homes.
