A near-total ban on abortions has been signed into law in the US state of South Dakota.
The bill would make it a crime for doctors to perform an abortion unless the procedure was necessary to save the woman's life. It would make no exception for cases of rape or incest, but such victims could get emergency contraception.
Under the new law, doctors could get up to five years in prison for performing an illegal abortion.
A judge is likely to suspend the abortion ban before it is due to take effect July 1st, however, which means it would not change state policy unless the case gets all the way to the US Supreme Court and the state wins.
Governor Mike Rounds, who supported the bill, said it was a "direct frontal assault" on the US Supreme Court decision to legalise the procedure 33 years ago.
The state legislature passed the bill last month after supporters argued that the recent appointment of conservative justices John Roberts and Samuel Alito have made the Supreme Court more likely to overturn the 1973 Roe v Waderuling.
The controversial judgment established that governments lacked the power to prohibit abortions.
Although Mr Rounds said he personally believed it would be better to chip away at abortion one step at a time rather than directly confront Roe v Wade, he said many abortion opponents thought otherwise.
Planned Parenthood, which runs the state's only abortion clinic, has not yet decided whether to challenge the measure in court or to seek a state-wide referendum in November, which would either repeal the abortion ban or delay a court challenge.
