Here's how one of the beaches looks now:
A pipeline leak spilled more than 13,000 gallons of oil into the Gulf of Thailand off Rayong province on Saturday, the Associated Press reported. The slick is now washing ashore on Samet Island.

Samet Island, famous for its white sands and emerald waters, draws around 1 million tourists every year.
Historically, this is Thailand's fourth major oil spill.
