Hebrew University Blast Kills 7, Injures Dozens

JERUSALEM — A bomb hidden in a bag ripped through a cafeteria at Hebrew University Wednesday, killing seven people, including three Americans, in an attack that shattered the peace in one of the few places where young Jews and Arabs still mixed freely.
Hamas1 claimed responsibility for the bombing and said it was the revenge for Israel's air raid last week on Gaza City that killed the organization's military chief, Salah Shehadeh, and 14 civilians, including nine children.
Israel decided to retaliate within hours, Israel Radio said.
U.N. Secretary-General Kofi Annan condemned the attack and again urged Israelis and Palestinians "to end the cycle of violence, revenge and retaliation."
