Indian Prime Minister Narendra Modi today led thousands of people in marking the fourth edition of International Yoga Day celebrations by performing breathing exercises and 'asanas.'

Clad in a white T-shirt and a pair of white trousers, Modi joined yoga performance on the lawns of the Forest Research Institute in Dehradun in Uttarakhand state early in the morning, reports our New Delhi correspondent.

He also led the chanting of the first round of 'Om'.

Indian Vice President M Venkaiah Naidu and several of Modi's cabinet colleagues also  took part in yoga events across the country, reports the correspondent.

Addressing the yoga enthusiasts, Modi said "yoga has emerged as the biggest unifying force in the world. Yoga binds the humanity, world, family and individuals. 

"The world has embraced Yoga and glimpses of this can be seen in the manner in which International Day of Yoga has been marked every year. In fact, Yoga Day has become one of the biggest mass movements in the quest for good health and well-being," Modi said.

The United Nations General Assembly, on a request by Modi, declared in December 2014 that June 21 be observed as International Day of Yoga every year.
