Swords crossed at the Golden Temple in Amristar, India, as Sikh activists and guards clashed during a commemoration of the Indian Army assault on the site in the 1984.

“The violence broke out after a group of ‘radical Sikh activists’ wanted to brandish their swords and chant slogans calling for a separate Sikh homeland, or Khalistan,” according to a NPR article, based on reporting by the Times of India.

The 1984 assault on the holiest Sikh religious site provoked retaliatory attacks by Sikhs, including the assassination of Indira Gandhi.
