Veteran Indian off-spinner Harbhajan Singh on Monday unconditionally apologised for a social media post in which he shared a picture of Khalistani militant Jarnail Singh Bhindranwale to pay homage to those who died in 'Operation Bluestar' of 1984.

The 40-year-old off-spinner said he posted a WhatsApp forward on the 37th anniversary of the operation without realising that the man in the picture was Bhindranwale.
