Officials say the clinic in Mexico where Coretta Scott King died has been shut down.

The health department in Mexico's Baja California state announced the closure of the Hospital Santa Monica Thursday because it was performing some procedures without authorization. The statement said the alternative-medicine clinic, located some 26 kilometers south of San Diego, was performing surgeries, X-rays and unconventional treatments without permission. It also said unknown substances were found there.

A spokesman for the clinic told the Atlanta Journal-Constitution newspaper Friday that Mrs. King was only receiving nutrition and had not yet started treatments. She checked into the clinic January 26, suffering from ovarian cancer and the effects of a stroke and heart attack sustained last year.
