The Tel Aviv District Court on Tuesday rejected an early release petition by Nahum Manbar who agreed to sell Iran chemical warfare material. Manbar petitioned the court after the Prison Service's release committee rejected his request. In its verdict, the court ruled that the committee's decision was right and reasonable. Manbar was not present in the courtroom since he is on leave from prison. Manbar was convicted in Tel Aviv District Court in 1997 of signing a contract with the Iranian government to supply it with know-how and chemicals for its military effort, and to help establish factories to produce the chemical weapons. He received $16 million in return.
