Islamic Jihad, a virulently anti-Israel group backed by Iran and Syria, claimed responsibility for Monday's suicide attack in Tel Aviv.
Islamic Jihad has claimed responsibility for eight of nine suicide attacks in Israel and the West Bank since the cease-fire declaration in February 2005, and its militants in Gaza continue to fire homemade rockets at Israel on a daily basis.
The 2,000-strong group arsenal includes M-16 and AK-47 automatic weapons, grenades and anti-tank weapons.
Islamic Jihad is led by Ramadan Shallah, a Palestinian from Gaza who now lives in exile in Syria. It considers the 1979 Iranian Revolution to be the beginning of a new era for the Muslim world, and wants to turn all of Israel, the West Bank and Gaza into an Islamic state. It rules out compromise with Israel.
