High occurrence of cancer has been detected in Israel's elite naval commando unit, apparently due to the waste disposal by Israeli firms in Kishon River.
The river, which flows into the Mediterranean Sea in the northern city of Haifa, has been used for training the unit, known as Shayetet 13.
Carmel Olefins Ltd., Israel's sole manufacturer of petrochemical products used in the plastics industry, as well as other firms have been accused of directing their waste into the river, which is notorious for being the most polluted stream in Israel.
