At least 12 people have been injured during clashes which broke out between Sikhs at Amritsar's Harmandir Sahib, or Golden Temple, the religion's holiest shrine, in northern India.
Kiran Jyoti Kaur, a spokesperson for the temple, told that members of a Sikh group brandishing swords and wooden sticks clashed on Friday with the guards of the shrine.
Hundreds of Sikhs had gathered at the temple to pay their respects to those killed in the June 6, 1984 raid of the temple by Indian troops, aimed at flushing out armed separatists demanding an independent Sikh homeland.
"Today we were supposed to have a solemn remembrance for the martyrs of 1984 so what has happened is very sad," Prem Singh Chandumajra, a spokesperson for a Sikh group called the Shiromani Akali Dal, whose supporters were involved in the clashes, told the AFP news agency. "The Temple has once again been dishonoured today."
