Security forces arrested an Israeli-Arab last month for smuggling raw bomb-making materials to a Hamas operative, Waal Zakle, 22, in Tulkarm, Army Radio reported.
The incident had been under a court gag order.
Muhammad Khalaf, from the village of Jatt, is suspected of smuggling sulfur and potassium, as well as other materials, in sacks filled with sugar.
According to a press release from the Prime Minister's Office, Zakle, who had been arrested by security forces, belonged to a cell that planned, organized and perpetrated several attacks in which Israeli citizens were wounded. Zakle said that he appealed to Khalaf and asked him for materials used in making explosives.
Khalaf will be indicted in a Tel Aviv District Court for security offenses of aiding an enemy in wartime, contact with a foreign agent, the illegal possession of a firearm, criminal conspiracy and attempted criminal conspiracy.
