TOPEKA (AP) – The Kansas Senate is preparing to take up legislation blocking tax breaks for abortion providers, but some lawmakers want to go further by pursuing a ban on most abortions after a fetal heartbeat is detected.

The measure on the Senate’s agenda for debate Tuesday or Wednesday not only deals with tax exemptions and credits for abortion providers but bars them from providing materials or instructors for sex education classes in public schools.

It also includes a statement that life begins at fertilization and is worth protecting. The measure has passed the House.

But a House committee heard testimony Tuesday on banning most abortions after a doctor can detect a fetal heartbeat, which can happen as early as the sixth week of pregnancy.

North Dakota Gov. Jack Dalrymple signed such a measure Tuesday.
