NEW ORLEANS La. (Reuters) - A federal judge on Sunday temporarily blocked a Louisiana law that advocates say would likely have closed of all five abortion clinics in the state.

The measure, signed into law by Louisiana Governor Bobby Jindal in June and due to take effect Sept. 1, would require doctors who perform abortions to have patient admitting privileges at a hospital within 30 miles of their practice.

However, the judge's ruling means that for the time being doctors can continue to perform legal abortions while seeking to obtain admitting privileges. A hearing will be held at a later date for the judge to make a more permanent ruling on the law.

"Plaintiffs will be allowed to operate lawfully while continuing their efforts to obtain privileges," Federal Judge John deGravelles wrote in the ruling.
