The faction has a small support base. Unlike the far bigger Hamas, which runs schools and hospitals, Islamic Jihad has no real social or political role.

The group is based in the Syrian capital, Damascus, and its financial backing is believed to come from there and Iran.

Islamic Jihad is committed to the creation of an Islamic Palestinian state and the destruction of Israel through holy war. It also opposes pro-Western Arab governments.

The Palestinian Islamic Jihad originated in the Gaza Strip during the 1970s.

Assassinated leader

It traditionally tries to carry out attacks against Israeli targets on the anniversary of its murdered leader Fathi Shaqaqi in Malta in October 1995.

The group operates primarily in Israel and the occupied territories, but has also carried out attacks in Jordan and Lebanon.

Other than Thursday's bomb attack in central Jerusalem, the most recent attack by Islamic Jihad took place on 17 July this year. A suicide bomber killed two Israeli soldiers in northern Israel.
