Thai soldiers in white biohazard suits take part in a clean-up operation at Ao Prao Beach on Koh Samet, Rayong July 29, 2013. Crude oil that leaked from a pipeline in the Gulf of Thailand over the weekend has reached a Thai tourist resort, pipeline operator PTT Global Chemical Pcl said on Monday. Around 50,000 litres of crude oil poured into the sea on Saturday around 20 km (12 miles) off the coast of Rayong, southeast of the capital Bangkok.
