The most restrictive abortion law in the United States was in effect for less than 24 hours before a federal judge temporarily blocked it Tuesday during what could become a long legal fight between Mississippi's Republican governor and the state's only abortion clinic.

The law's only exceptions are if a fetus has health problems making it "incompatible with life" outside of the womb at full term or if a pregnant woman's life or a "major bodily function" is threatened by pregnancy. Pregnancies resulting from rape and incest aren't exempted.

The clinic, Jackson Women's Health Organization, quickly sued, arguing the law is unconstitutional because it bans abortion weeks before a fetus can survive outside the womb.
