[The Qassam rocket is a simple steel artillery rocket developed and deployed by the Izz ad-Din al-Qassam Brigades, the military arm of Hamas. Three models have been produced and used between 2001 and 2011.
More generally, all types of Palestinian rockets fired into southern Israel, for example the Palestinian Islamic Jihad Al Quds rockets, are called Qassams by the Israeli media, and often by foreign media.
The Qassam gained notoriety as the best-known type of rocket deployed by Palestinian militants against Israeli civilian and military targets during the Second Intifada of the Israeli–Palestinian conflict. Since 2000, Palestinian rockets have claimed the lives of 22 Israelis and one Thai national]. – Wikipedia
