2003 Nasiriyah bombing

The 2003 Nasiriyah bombing was a suicide attack on the Italian Carabinieri MSU headquarters in Nasiriyah, Iraq, south of Baghdad on 12 November 2003. The attack resulted in the deaths of 18 Italian servicemembers, mostly members of the MSU Carabinieri, an Italian civilian, and 9 Iraqi civilians and was the worst Italian military disaster since the Second World War. The attack, labeled a "terrorist act" by Italian president Carlo Azeglio Ciampi, was among a string of many attacks on non-American military international targets in Iraq that occurred shortly after the end of major combat operations, including the Jordanian and Turkish embassies, International Red Cross, and UN facilities.
