Southern California spill leaks at least 126,000 gallons of oil into ocean and closes beaches

An offshore rig has leaked 126,000 gallons of oil in the Pacific Ocean so far, leading to what one Southern California mayor called a "potential ecological disaster." Authorities said Sunday that a "very large sheen" was approaching Orange County beaches, which have been closed. 

"Our wetlands are being degraded and portions of our coastline are now covered in oil," said Huntington Beach Mayor Kim Carr on Sunday. 

The cause of the spill remained undetermined on Sunday afternoon.
