As many as 47 per cent of Israelis believe their security agencies are not doing enough to combat Jewish terrorist attacks, a new poll has revealed.

The poll, conducted by Panels, also showed that 40 per cent think political considerations play a part in the way Jewish terrorism is handled in Israel.

According to the poll, 58 per cent believe there is sufficient evidence and legal procedures to deal with Jewish terrorism while 30 per cent believe the security forces do not possess any legal evidence.

The new poll comes after Israeli media reported a significant development in the investigation into the firebombing attack believed to have been carried out by Jewish extremists that killed a child and his parents in July.

Israeli authorities have said that some of the suspects may have already been held under administrative detention.
