LITTLE ROCK, Ark. (AP) - The Arkansas House has approved a proposal banning abortion 18 weeks into a woman's pregnancy, moving the state toward enacting what could be the strictest prohibition in the country.

 The House on Monday approved the ban by a 77-13 vote. The measure now heads to the state Senate.

 Arkansas already has some of the strictest abortion laws in the country and bans the procedure 20 weeks into a woman's pregnancy. The state's Republican governor last week signed into law legislation banning abortion if the U.S. Supreme Court overturns its 1973 Roe v. Wade decision that legalized the procedure nationwide.
