Thousands of British Sikhs gather in central London to commemorate the anniversary of the 1984 Amritsar massacre.

The Sikh community showed up in their masses for an issue that is of huge significance to their community.

In 1984, the Indian army stormed the Golden Temple in Amritsar - the holiest shrine for Sikhs - with the aim of removing armed Sikh dissidents who sought the creation of an independent homeland, called Khalistan.
