A decree declaring three days of official mourning was issued by the government, and five minutes of silence were observed on Friday. Demonstrations were called for Friday evening in cities across the country, under the motto ""With the victims, with the constitution and for the defeat of terrorism"". The Catalan government led by Pasqual Maragall also declared official mourning in Catalonia. The government's chosen motto was very criticized by all the opposition because the ""with the Constitution"" inclusion in the motto implied that the bombs were set by the ETA, while many in the opposition believed that it was made by an Islamic group in retaliation for having Spanish troops in Iraq.
