UK Sikhs march over Amritsar 'genocide'

Members of the Sikh community have marched through central London in protest at the storming of India's Golden Temple 30 years ago.
Thousands attended the event, where it was demanded that the assault of June 1984 be recognised as a genocide.
Sikhs say thousands were murdered when Indian Prime Minister Indira Gandhi sent the army into Sikhism's holiest shrine to flush out militants.
