"Matt and Sara's names are absent and rewards for terrorists not offered," said Matt's father, Dr. Leonard Eisenfeld, referring to the Web site. "Peace can only exist alongside justice."

The Rewards for Justice site — www.heroes.net — serves as an interim homepage for the State Department's Diplomatic Security Service. According to the site, rewards totaling millions of dollars have been paid in dozens of cases. The program was established in 1984, and the Web site has been active since 1995.

State Department spokesman Andy Laine said the department is looking into offering rewards for terrorists responsible for killing Americans in Israel, and is also considering adding Palestinian terrorists to the Web site.

Regardless, he said, the rewards apply to all acts of international terrorism. So if someone were to come forward with information on a Palestinian terrorism case in Israel, the person would be eligible for a reward.

Since the Oslo peace accords were signed in 1993, 12 Americans have been killed by Palestinian terrorists in Israel.
