"We intend to ask prosecutors to indict the three journalists as with their illegal acts they not only put their lives in danger, but also the security of Israel," the officer in charge of the case, Alon Sharabani, told public radio.

He named the reporters as Ron Ben Yishai of the mass-selling Yediot Aharonot daily who in September traveled to Syria, and two journalists who traveled to Lebanon - Lisa Goldman of the private Channel 10 television and Tzur Shizaf of a geographic magazine.

The three reporters hold both Israeli and foreign passports, on which they entered the "enemy states" - countries with which Israel is technically at war.

Israeli legislation prohibits the citizens of the Jewish state, even those who hold multiple nationalities, from traveling to "enemy states" without permission from the interior ministry - an offense that can be punishable with up to four years in prison.

Israel has been in a technical state of war with Lebanon and Syria since 1948, when the Jewish state was created.
