Sources said the missiles were probably the Strela-2/SA7, a Soviet-era shoulder mounted missile.
This is the first time these missiles were used by Gaza terrorists, althoughthere have been reports that Gaza groups had them for years. As early as 2001, Israel intercepted a weapons ship headed towards Gaza that included Strela missiles.
When Libya fell there were numerous reports about sophisticated weapons flooding the region.Last January, weapons smugglers in the Sinai claimed that they sold thousands of surface-to-air missiles from Libya to Gaza - but kept some for themselves for eventual use against Egyptian forces.
