Describing the event as "da ghallughara (holocaust) of 84", Jathedar Akal Takht Gyani Harpreet Singh stressed on maintaining unity among the Sikh community.
Terming the 1984 riots as a "genocide", a meeting of five Sikh high priests convened by the Akal Takht, the highest temporal seat of the Sikh religion, said it was "regrettable" that justice could not be delivered to the victims even after 25 years.
Making an early morning trip to the holiest Sikh shrine, Dr Singh accompanied by his wife Gurusharan reached the complex at 6 am and spent an hour there.
The 31st anniversary of Operation Bluestar on Saturday went off peacefully amid tight security arrangements here even as Shiromani Akali Dal.
