Shark sighting off San Onofre beach prompts warning

SAN ONOFRE, Calif. -- A shark sighting prompted a public warning Friday for visitors to San Onofre-area beaches.

Surfers reported seeing an 8- to 10-foot shark in a surf break known as Old Man's, according to officials at Camp Pendleton, whose property includes a stretch of ocean shoreline in the vicinity.

The alert will last for 24 hours, until late Saturday afternoon, authorities advised.

On April 29, a shark attack in the same general area left a woman severely injured.
