Police arrested about 100 demonstrators Saturday who were blocking the entrance to a health clinic where abortions are performed, authorities said.

About 30 protesters continued the anti-abortion protest on the sidewalk outside of the Sigma Women's Center following the arrests, but the clinic's administrator said the staff was conducting business as usual.Ott Cefkin, a spokesman for the Fort Lauderdale Police Department, estimated that 150 to 200 people from a group calling itself Rescue South Florida took part in the protest.

No one was injured in the demonstration, although the staff and some patients of the clinic were frightened, Cefkin said.
