U.S. abortion rights activists had already vowed to go to court to block enforcement of the Alabama measure, the strictest anti-abortion law yet enacted with the intention of provoking reconsideration of the 1973 Roe v. Wade ruling.
That effort has thrust the emotional debate over abortion back to the forefront of national politics in the run-up to the 2020 U.S. presidential elections.
Governor Kay Ivey, a Republican, signed the measure a day after the Republican-controlled state Senate approved the ban and rejected a Democratic-backed amendment to allow abortions for women and girls impregnated by rape or incest.
“To the bill’s many supporters, this legislation stands as a powerful testament to Alabamians’ deeply held belief that every life is precious and that every life is a sacred gift from God,” Ivey said in a statement.

Abortion supporters across the country condemned the bill as part of a Republican-backed assault on the rights of women to control their own bodies.
“This is the war on women,” said California Governor Gavin Newsom, a Democrat, “It’s in full swing, and it’s decades in the making.”
The Alabama law would take effect in six months.
Legislation to restrict abortion rights has been introduced this year in 16 states, four of whose governors have signed bills banning abortion if an embryonic heartbeat can be detected.
