Gaza power plant engineer Dirar Abu Sisi, who was reportedly taken into custody from the Ukraine in March and brought to Israel, provided a rare in depth look at Hamas attempts to develop longer-range rockets aimed at Israeli civilians and efforts to improve its military capabilities following Operation Cast Lead.
The Beersheva Magistrate's Court released sections of the investigation by security forces of the Abu Sisi for publication on Thursday.
Abu Sisi is charged with national security offenses, conspiracy to commit murder, and being active in a terrorist organization.
According to a report by Channel 10, during questioning, Abu Sisi described Hamas as a hierarchical organization which seeks to learn from mistakes and to constantly improve its attack capabilities against Israel.
He reportedly confessed to carrying out rocket experiments, during which projectiles were fired out to the Mediterranean Sea from Khan Younis. "The rocket fell [into the water] after 22 kilometers, thought it was supposed to fall after 30 kilometers" he said during questioning, according to Channel 10.
