Alabama Gov. Kay Ivey just signed the state’s controversial near-total abortion ban. The new law is the most restrictive anti-abortion measure passed in the United States since Roe v. Wade was decided in 1973.

The legislation — House Bill 314, “Human Life Protection Act” — bans all abortions in the state except when “abortion is necessary in order to prevent a serious health risk” to the woman, according to the bill’s text. It criminalizes the procedure, reclassifying abortion as a Class A felony.
