Indian Prime Minister Narendra Modi and more than 35,000 people took part in a mass yoga programme,
setting a new Guinness World Record for the largest yoga class at a single venue.
There was some controversy about it domestically, though :
when some from India's Muslim minority worried about a "Hindu agenda"
Then came the Twitter storm.
It happened because some noticed that India's Vice-President Hamid Ansari
- who is Muslim - was not present at the event
Ansari's office responded that he was "never invited" to the event.
"The vice-president only attends those programmes in which the minister concerned invites him as per protocol,"
Shripad Yasso Naik, who presides over for AYUSH (Ayurveda, Yoga and Naturopathy, Unani, Siddha and Homeopathy),
then clarified that the invitation was not sent due to a "warrant of precedence".
"When we call the prime minister, we cannot call the vice-president… We invited everyone, all the ministers, all the chief ministers,
but according to the rule we couldn't send Ansari an invitation.
I have admitted my mistake. It must have been avoided. Mistakes are made, we are only humans,"
