Pro-life protesters clashed with abortion advocates staging a vigil outside a women's health center on Southern Boulevard Saturday.

The New York Coalition for Abortion Defense has launched its own 40-day vigil outside A Bronx Women's Medical Pavilion at 560 Southern Blvd., chanting slogans, displaying pro-choice signs and calling anti-abortion activists 'bigots.'

Pro-choice advocates say abortion protesters harass women, chase them down the street and even attempt to physically block them from entering abortion clinics.
