The parents of US peace activist Rachel Corrie on Thursday marked the fifth anniversary of her death with a small West Bank memorial. Corrie was 23 when she was run over by a 60-ton Israeli bulldozer in Gaza in 2003. At the time, was trying to prevent a Palestinian home from being demolished. The driver said he didn't see her, and the Israeli military ruled her death accidental. Corrie was from Olympia, Washington. Her parents have repeatedly returned to the Palestinian territories, including to the spot where she was killed. On Thursday, about 150 Palestinians and foreigners attended a memorial, gathering in a street in the West Bank city of Nablus, led by Corrie's parents, Cindy and Craig. Some held up photos of Rachel.
