When did the group begin to target civilians inside Israel?

Experts say the shift began in early 2002, when the Palestinian death toll in the current uprising was nearing 1,000 and the popularity of Arafat's secular Fatah faction was waning in comparison to the Islamist militants of Hamas. A 2007 poll by Pew (PDF) Research Center says that many Palestinians support suicide bombings as an effective means of attack.

The Al-Aqsa Martyrs Brigade attacks became more deadly after January 2002, when the group's West Bank leader, Raed Karmi, was killed in an explosion widely believed in the region to have been a "targeted killing" by Israeli forces.
