Free-flight artillery rockets lacking any guidance system. In the context of the Israeli-Palestinian conflict, they are produced primarily by Hamas and other groups in the Gaza Strip. About 6,332 Qassam rockets have been launched into Israel from Gaza since 2005, landing frequently in the southern city of Sderot. The rockets have a maximum 10-15 km range, and have caused property damage as well as occasional infrastructure damage. Israeli defense specialists consider the Qassam rocket to be more of a psychological threat than a physical threat. Between June 2004 and August 2011, 19 Israelis and two foreign nationals were killed by rocket and mortar attacks on Israeli towns or cities along Gaza’s border.
