OKLAHOMA CITY (AP) - Oklahoma Attorney General Scott Pruitt is asking the U.S. Supreme Court to review a decision by the Oklahoma Supreme Court that invalidated a state anti-abortion statute.

The state's highest court ruled in December that the anti-abortion law was ``facially unconstitutional'' and that a lower court judge was right to prevent its enforcement. The law restricted the off-label use of certain abortion-inducing drugs, such as RU-486.

Pruitt said in a statement on Tuesday that Oklahoma's law - passed by state lawmakers in 2011 - does not ban the drugs but requires proper protocols to be followed. He says there is strong evidence that the off label use of abortion-inducing drugs leads to serious infections and death for many healthy, unsuspecting women.

Pruitt's appeal, filed on Monday, challenges the state Supreme Court's ruling.
