Many of the "Kassam" type rockets that Gaza terrorists use to attack Israel and make life in the Sderot area unbearable are manufactured with Israeli pipes. This information surfaced after the arrest of a Gazan metal trader last month and his interrogation - the details of which were under a gag order until now.

The Gazan, Amer Zak, 37, admitted that he used to buy pipes and other metal parts from Israeli companies, then sell them to terror organizations for the manufacture of Kassam rockets.

Zak told police and Shabak interrogators that he used to sell pipes of certain diameters to Hamas turneries and to senior members of Hamas' manufacturing arm.
