The US state of Iowa has approved an abortion law banning most abortions once a foetal heartbeat is detected.
Republican lawmakers passed the bill in back-to-back votes, sending it to the governor’s desk to sign into law.
If it comes into effect the bill will ban most abortions after six weeks of pregnancy, and rights groups say it will be the country’s most restrictive.
Critics argue it makes having an abortion illegal before most women even realise they are pregnant.
Iowa’s Republican governor Kim Reynolds has not said if she will sign the bill.
Republican Representative Shannon Lundgren told local media this week that she believes the bill will become law.
“We’re in the majority for a reason and that includes advancing the pro-life cause,” Ms Lundgren told the Waterloo-Cedar Falls Courier.
Last year, Iowa Republicans successfully banned abortions after 20 weeks of pregnancy.
“We are alive when our hearts start beating and our life is over when it stops,” Dawn Pettengil, another Republican Representative from Iowa, told CBS News.
Democratic Representative Beth Wessel-Kroeschell spoke against the legislation on the floor of the Iowa House of Representatives on Tuesday.
“All women, regardless of age, income or race, should be able to obtain reproductive health services, including abortion, free from political and economic barriers,” Ms Wessel-Kroeschell said.
Other Iowa Democrats called the bill “intentionally unconstitutional”.
