"This is the third International Yoga Day and we have basically an amalgam, a mix of all different yoga schools here in one place," said volunteer Yuav Yenen.
Other mass yoga sessions were held in China, Colombia, the United States, Mexico, Paraguay, Italy, Singapore and atop Machu Picchu, a 15th century Inca citadel in Peru.
