JERUSALEM, Feb. 25 (JTA) — The more than two dozen people killed in a Jerusalem bus bombing a year ago were remembered by family and friends at a memorial service at the attack site. Among those present was the sister of Sara Duker, one of two American students killed in the suicide bombing by Islamic fundamentalists on Feb. 25, 1996. The other student was Duker’s boyfriend, Matthew Eisenfeld. At the ceremony, Jerusalem Mayor Ehud Olmert dedicated a plaque. Also on this day a year ago, a suicide bomber blew up a soldiers’ hitchhiking station near Ashkelon. Exactly one week after the February attack, a suicide bombing occurred on another bus on the same early morning route — No. 18 — in Jerusalem.
