A march has been held in London to remember those killed in the storming of Sikhism's holiest shrine, the Golden Temple of Amritsar, 21 years ago.
The Golden Temple is Sikhism's holiest shrine
On 6 June, 1984, Indian Prime Minister Indira Gandhi sent the army into the temple to flush out militants.
There has never been agreement on the numbers killed, but Sikhs say thousands were massacred by Indian troops, many of them innocent bystanders.
The Sikh Federation march in central London ended with a rally.
The military action 21 years ago led to Mrs Gandhi's assassination later that year by her Sikh bodyguards.
That in turn triggered a wave of anti-Sikh rioting which left nearly 3,000 dead.
"Sikhs from all generations took part in the protest," a spokesman for the Sikh Federation said of the London march.
"Many of the youngsters taking part were too young or not even born in June 1984 but demonstrated a great passion for seeking justice."
He added that some young people "were seen burning an effigy of Indira Gandhi near the Indian High Commission".
Liberal Democrat MP Simon Hughes addressed the rally, condemning human rights abuses in India and supported calls for Sikhs to be granted the right to self-determination.
