On Sunday morning (7 Oct 2007), Palestinian terrorists in the Hamas-controlled Gaza Strip fired a Grad missile, which landed near the southern Israeli town of Netivot - about 15 km inside Israeli territory. The 122 mm Grad heavy artillery rocket, apparently produced in the former Soviet Union and smuggled into Gaza from Egypt, is an improved version of the infamous Katyusha rocket recently used by the Hizbullah to bombard northern Israel from Lebanese territory.
