British relatives of people believed to have been taken hostage in the recent Hamas raids in Israel have appealed for their release and begged for help to find their families. Noam Sagi, 53, said he just wanted to bring his mother, a teacher, home after she disappeared when Hamas raided the Nir Oz kibbutz on Saturday. Artist Sharon Lifschitz, 52, said their ageing parents were helpless victims who could do no harm to anyone
