Another federal lawsuit has been filed challenging new provisions in Texas' tough restrictions on abortion.
It comes less than a week after a federal appeals court reversed a previous legal challenge.
The Center for Reproductive Rights asked an Austin-based federal judge Wednesday to block key portions of the law.
The suit mounts the first challenge to a provision of the law taking effect Sept. 1 and requiring that abortions take place in ambulatory surgical centers. The suit claims that would force clinics to undertake facility upgrades so costly that all but "fewer than 10" in a state with 13 million women would close.
The law also requires abortion doctors to have hospital admitting privileges within 30 miles of the clinic where they perform the procedure. The suit challenges that.
