The Tel Aviv-Jaffa Municipality will hold a memorial ceremony this evening for the 21 victims of the Dolphinarium attack. A suicide terrorist murdered the 21 exactly one year ago by blowing himself up amongst a group of young people, mostly new immigrants from Russia, waiting to enter the discotheque. Mayor Ron Huldai and the victims\' families will take part in the ceremony. The blast had been the worst Israel suffered during the current Oslo War until the Pesach Seder Massacre two months ago, which claimed the lives of 29 Jews.
