Louisiana lawmakers have passed a bill banning abortions once a fetal heartbeat is detected, joining a string of other US states restricting the termination of pregnancies as early as six weeks.
The bans are expected to be blocked in lower courts, but supporters plan to appeal such decisions until they reach the Supreme Court. 
They hope this will lead to the long-sought conservative goal of overturning the landmark 1973 ruling known as Roe v Wade, which recognized women’s right to abortion.
The measure — which includes exceptions for cases in which a woman’s life is at risk or the fetus has a fatal condition — passed the Louisiana House of Representatives with a vote of 79-23 after being approved in the Senate by 31-5, according to the legislature’s website.
It now goes to the desk of the governor, who said he plans to endorse it.
“As I prepare to sign this bill, I call on the overwhelming bipartisan majority of legislators who voted for it to join me in continuing to build a better Louisiana that cares for the least among us and provides more opportunity for everyone,” Governor John Edwards said in a statement posted on Twitter.
