LITTLE ROCK — A House committee has approved a pair of bills that would restrict most abortions in Arkansas. One would ban most abortions 12 weeks into a pregnancy and another would ban them at 20 weeks.

The 12-week ban passed the Public Health, Welfare and Labor Committee on Tuesday after previously falling short of the votes needed to move on. The proposed ban is based on when a fetal heartbeat can be detected by abdominal ultrasound.

The 20-week ban was developed on the disputed belief that an unborn child can feel pain at that point. Other states have approved similar restrictions.

Both bills passed on voice votes.

Gov. Mike Beebe has questioned whether the bills are unconstitutional but hasn't said whether he will veto either of them.
