OKLAHOMA CITY (AP) -- The Oklahoma House has given final approval to a Texas-style abortion ban that prohibits abortion after about six weeks of pregnancy.

The bill passed Thursday by the GOP-led House now heads to Republican Gov. Kevin Stitt. He's expected to sign it within days.

The bill was immediately challenged in court by abortion rights advocates.

The measure prohibits abortions once cardiac activity can be detected in an embryo.

Experts say that's typically about six weeks into a pregnancy, before many women know they are pregnant.

Like Texas, the bill allows private citizens to sue abortion providers or anyone who helps a woman obtain an abortion for up to $10,000.

The U.S. Supreme Court allowed a similar law in Texas to stand.
