Thousands of yoga aficionados celebrated the summer solstice amid the neon lights and cacophony of Times Square Wednesday, searching for inner peace in the heart of New York on International Yoga Day. Around 12,000 people were expected to take part in six one-hour yoga classes beginning at 7:30 a.m. (1130 GMT) to celebrate the official start of summer and the longest day of the year. The event is now in its 15th year. For the last three years, it has coincided with International Yoga Day.
