Israel's Shin Bet security agency says it has arrested six Bedouin for establishing a cell supportive of the Islamic State group.

The agency said Monday that four of those arrested were teachers and tried to indoctrinate students at their schools with the extremist group's ideas.

It said they intended to travel to Syria and fight for the Islamic State group, which controls about a third of Iraq and Syria. The group governs its self-styled caliphate in accordance with an extreme interpretation of Islamic law, carrying out cruel and often choreographed killings.

Shin Bet said the men were from Hura, a Bedouin township in the Negev desert. Bedouin make up a small group within Israel's Arab minority, numbering about 180,000.
