The Beersheva District Court convicted on Sunday a Hamas-affiliated terrorist charged with committing numerous crimes against Israel's security.
Dirar Abu Sisi, the former deputy engineer for Gaza's electrical plant, was indicted in April 2011 for "membership in a terror organization, conspiracy to commit a crime, the production of illegal weaponry, and assistance to an illegal organization."
According to the indictment, after Operation Cast Lead in 2009, Abu Sisi was appointed by arch-terrorists Muhammad Deif and Ahmed Jabari to establish a military academy for hostile activity against the Jewish state.
Abu Seesi is also alleged, according to the indictment, to have served as the commander of Hamas' Izz ad-Din al-Qassam Military Academy.
In addition to his connections to the military academy, Abu Sisi was also a senior partner in the production of both missiles and mortars, as well increasing the range of rockets launched by Hamas into Israel.
According to the indictment, Abu Sisi was the central developer of the Qassam rocket, among other rockets and anti-tank missiles.
Abu Sisi was convicted on five separate charges based on his own confession. The Southern District Attorney's Office is asking for a prison sentence of 21 years.
