Following the proliferation of violence perpetrated by illegal migrant workers in south Tel Aviv, a special self-defense workshop was held for senior citizens on Wednesday. The seminar was organized by the Police Department, the Immigration Policy Center and a senior citizens committee. The class covered such topics as muggings, thefts, attempted kidnappings and rape. The large influx of migrants crossing into Israel from the southern border has elicited support from sympathetic refugee assistance groups and disdain from local residents who have complained of the crime increase. Several recent Knesset sessions have sought to repatriate the migrants to their homelands.
