A teen from the northern Bedouin town of Shibli was set to be charged on Monday with membership in a terrorist organization, after he allegedly pledged allegiance to Islamic State.

Yaqoub Shibli, 19, was arrested on August 16, and his interrogators learned he “expressed identification with the Islamic State terrorist organization, including watching content about the terrorist organization and pledging allegiance to it,” police and the Shin Bet said Monday in a joint statement.

The Northern District Attorney’s Office is slated to indict Shibli on Monday at the Nazareth-Nof Hagalil Magistrate’s Court, the statement said.

It added that this is the fourth time in recent weeks that a resident of northern Israel faces an indictment for allegedly joining Islamic State.

“The Shin Bet and Israel Police act resolutely against any activity that endangers the security of the state and its citizens, and against any activity in which Israeli citizens seek to act against Israelis on behalf of a terrorist organization,” the security agencies said.
