Police arrested almost 200 anti-abortion activists at two Atlanta clinics Tuesday as the opening round of what protest organizers say will be a four-day "Siege of Atlanta" got under way.

"They're blocking the street, they're failing to disperse, so we're locking them up," said Police Capt. W.W. Holley.More than 100 demonstrators arrived at one midtown abortion facility about 10:40 a.m., many of them crawling up the street toward the small brick building. When some tried to go beyond a temporary fence installed outside the clinic, police began dragging the protesters away toward waiting buses and vans. About 75 were arrested.

A mile away, another protest began at another clinic. There were two groups demonstrating - one which made attempts to get inside the building, and another which sat on the ground singing hymns.
