Shin Bet internal security forces in a joint operation with Israeli police have broken up an ISIS (Islamic State) terror cell in northern Israel.

The six cell members were all based in the Arab town of Jaljulya, near Kfar Saba, and had planned to travel to Syria to join the jihadists' ranks there.

The group was revealed after another Jaljulya resident, 23-year-old Nedal Ahmed Salah Salah paraglided across Israel's northern border with Syria in October to join jihadists there.
