The Shin Bet security service and the Israel Police arrested Israeli Arab Hassan Khaled Taher Sheikh Yusef, 26, from the Arab city of Taibeh in central Israel, on suspicion of supporting the ISIS terror organization, and intentions to carry out an attack inspired by the organization.

The investigation found that between the years 2014-2015 Yusef began strengthening his Islamic observance and approached the ISIS organization, during which time he viewed ISIS-related Internet content and explored possibilities of joining the organization in Syria.

The investigation also indicated that Yusef had viewed training material for preparing explosives and even tried to convince another to purchase an M16 rifle with him.

During the summer of 2017, in parallel to the Temple Mount magnetometer riots, Yusef tried to persuade others to join him in carrying out various attacks, including a Jerusalem shooting attack, a car bomb attack in front of the Taibeh police station, and a stabbing attack.

All those whom he approached to join him scorned his proposals and disavowed him. Thus, with his intentions frustrated, Yusef was afraid to carry out an attack independently.

Yusef's interrogation was accompanied by the Central District Prosecutor's Office, which today filed an indictment against him.

"The General Security Service views Israelis who support the ISIS organization as a serious security threat, and will therefore continue to monitor suspects carefully and take necessary enforcement measures to prevent the organization from spreading its ideology in Israel, as well as the departure of Israelis to fight in the organization's ranks," the Shin Bet said.
