The killing of a 10-year-old Palestinian girl in the West Bank has cast a pall over Palestinian and Israeli peace activists. Israeli investigators are questioning border police who were involved in a clash with Palestinians in Anata, during which the girl was slain.

The mood in Anata is angry. But the girl's father, a militant who became a peace activist, says his daughter's death makes him want to work harder for a solution to the Israeli-Palestinian conflict.
