Hamas and another Palestinian militant group have claimed responsibility for what appeared to be a failed bombing attack in the Israeli city of Tel Aviv that killed the attacker and wounded a bystander. The late Sunday blast came as mediators were working on a cease-fire agreement in the devastating Israel-Hamas war. The bomb appeared to have gone off before it was intended, and it was unclear whether the attacker planned to carry out a suicide attack or plant the explosives and set them off remotely. Tel Aviv’s district police commander told reporters the blast occurred near a synagogue filled with people at evening prayers.
