Several U.S. states immediately banned abortion on Friday in the wake of the Supreme Court’s ruling that overturned Roe v. Wade, dividing the nation between jurisdictions where the procedure is legal and where it is outlawed. The high court’s decision ended a half-century of constitutionally protected abortion rights, which means that states will now be allowed to regulate the procedure. At least 13 states have laws on the books that either ban abortion immediately or will do so soon. Abortion bans in Arkansas, Kentucky, Louisiana, Missouri, Oklahoma, South Dakota, Utah and Alabama went into immediate effect. The laws make performing an abortion a felony punishable by years-long prison sentences. They do not make exceptions for rape or incest. However, women cannot be prosecuted for receiving an abortion under the laws.
