South Carolina's governor, Republican Henry McMaster, has signed the most restrictive abortion law in the United States, one that prohibits termination of pregnancy after six weeks of gestation.
It is the period in which the first heartbeat of the fetus is usually detected but in which many women do not yet know they are pregnant.
Doctors who perform abortion beyond this period will face sentences of up to two years in prison.
"We will become the most pro-life state in the country," McMaster cheered on Twitter days ago.
