AUSTIN (AP) -- As protesters chanted in the rotunda of the state Capitol, Texas Gov. Rick Perry signed into law sweeping new abortion restrictions that sparked weeks of protests.
Carrying letters that spelled "shame," the protesters chanted "The blood of Texas women is on your hands."
More than 100 Republican lawmakers attended the signing ceremony.
The new law bans abortions after the 20th week of pregnancy and dictates when abortion-inducing drugs can be taken. But it also requires abortion clinic doctors to have hospital admitting privileges and restricts abortions to surgical centers. Only five of Texas' 42 abortion clinics currently meet the new requirements.
The law will take effect in October and clinics will have a year to upgrade their facilities or shutdown. Perry said the new law "builds upon our commitment to protecting life in the state of Texas."
The governor and other top Republican politicians in the state made passing the law a top priority, in part to please supporters before the primary election in March. They failed to pass the bill last month on the last day of a special legislative session because of a Democratic state senator's lengthy filibuster and a raucous crowd. But they were successful last week after Perry called a second special session to get the bill approved.
Lt. Gov. David Dewhurst said Thursday that the "radical left" had inflicted "intentional chaos" that delayed the bill's initial passage. He credited prayer and even "the hand of God" in making Thursday's event happen, as about 25 protesters could be heard chanting "Shame! Shame! Shame!" out in the hallway.
Supporters of the law argue that it will ensure high-quality health care for women and fetuses, but opponents view it as over-regulation intended to make abortions harder to obtain.
Federal judges have blocked enforcement of similar measures in other states, questioning their constitutionality. Opponents are expected to file similar suits in Texas now that Perry has signed the law.
