A shark attack Friday killed a 20-year-old man off a beach on Vandenberg Air Force Base, said the Santa Barbara County, California, Fire Department.
Surf Beach is one of three that sits on the coastal air base, and the military closed all three beaches at 9:46 a.m. Pacific (12:46 p.m. ET), shortly after the shark attack, an air base spokesman said.
The three beaches will remain closed for 72 hours, the spokesman said.
Surf Beach is open to the public, but the other two -- Wall and Minuteman Beaches -- are open to base personnel only, the spokesman said.
