Thousands of devotees early in the morning thronged the Akal Takht the highest temporal seat of Sikh religion to attend the 'bhog' ceremony of religious prayers that began on June 4.
The prayers were to mark the anniversary of Operation Bluestar that was carried out in June 1984 by the Indian Army to flush out heavily armed terrorists from inside the Golden Temple complex.
Security agencies were put on high alert in and around this city in view of the anniversary.
Punjab Police, paramilitary forces and intelligence personnel were stationed at different locations across the city, particularly around the Golden Temple complex.
The radical Sikh organisation Dal Khalsa called for a shutdown in Amritsar to protest against the Army action.
Acting Jathedar of Akal Takht Giani Harpreet Singh and Shiromani Gurdwara Parbandhak Committee (SGPC) President Gobind Singh Longowal had appealed to the public to maintain peace while observing the anniversary.
A day ahead of the anniversary, the Jathedar said Parliament should accept that the attack carried out on the directions of the Indian government was a blunder and should submit an official apology for it.
"The Indian Parliament should bring 'maafi da matta' (an apology resolution) for the execution of Ghallughara (Operation Bluestar) in 1984," he said in a statement.
Parallel Jathedar of Akal Takht, Dhian Singh Mand, participated in the culmination event.
Pro-Khalistan groups like the Dal Khalsa and Shiromani Akali Dal (Amritsar) led by Simranjit Singh Mann held 'remembrance marches' in the city.
On the anniversary of Operation Bluestar in 2014, a clash between radical Sikh activists and the task force of the SGPC had taken place in which several people were injured in the Golden Temple complex.
