On Tuesday night, during a discussion of the Foreign Affairs and Defense Committee, Shas MK Nissim Zeev drank water that may have been poisoned. At the end of the discussion, Zeev began to feel unwell and was checked out by the Knesset's doctor, Dr. Yitzhak Lifshitz, who decided to do more in-depth tests, Army Radio reported Wednesday. According to Zeev, the doctor took blood and urine from him. Zeev began to feel better after several hours and was present in the plenum on Wednesday. Other members of the committee said the water in the pitcher had been a strange color and could have been poisoned. Dr. Lifshitz decided not to take any chances and has asked the police forensic unit to investigate.
