A clash between Sikhs wielding swords inside the compound of their religion's holiest shrine on Friday injured at least seven people, including a child, Reuters reported.

Task force volunteers of the Shiromani Gurdwara Parbandhak Committee (SGPC) and radical Sikh activists clashed on the 30th anniversary of a controversial raid by Indian security forces that flushed out separatist militants holed up in the temple.

The violent confrontation saw Sikhs rushing out of the Golden Temple in Amritsar, northern India, brandishing their swords against each other, television's dramatic footage showed.

As the victims of the 1984 temple raid were being commemorated, the incident was triggered by a minor argument, a police official said.

Eyewitnesses said the clash occurred when activists of the Shiromani Akali Dal (Amritsar) were stopped by the SGPC task force volunteers from brandishing swords and other traditional weapons and raising pro-Khalistan slogans inside the complex, The Hindu reported.

Peace has since been restored, said the official, who declined to be named because he is not authorized to speak to the media, according to Reuters.

"The violent clashes will be investigated and action will be taken against those who are accused," said Giani Gurbachan Singh, a leader of the elected body that manages Sikh temples.

In June 1984, heavily armed terrorists, led by separatist leader Jarnail Singh Bhindranwale, were flushed out of the Golden Temple complex by the Indian Army in its Operation Bluestar, according to The Hindu.

Sikh bodyguards had then assassinated former Prime Minister Indira Gandhi in 1984 over the army's storming of the temple.

Nearly 3,000 people were killed in retaliatory riots against the Sikhs.

India has suffered an upsurge of violence in many forms since a general election last month won by Prime Minister Narendra Modi's Hindu nationalist Bharatiya Janata Party (BJP).

"In the most heinous crime, two girls were raped and hanged in a village in the northern state of Uttar Pradesh. Three men have been arrested over the killing, and two policemen suspected of helping to cover up the crime," according to Reuters.

"This week, a lynch mob in the western city of Pune killed a Muslim information technology worker. Seventeen men with links to a little-known radical Hindu group have been arrested over the killing, apparently provoked by a controversial Facebook post."
