India's parliament was thrown into chaos Tuesday after the ruling Congress party rejected a report suggesting a government minister played a role in riots in 1984 that killed more than 3,000 Sikhs.

Jagdish Tytler, now a junior minister, was named in the report as having instigated some of the Hindu-led violence in the days after Sikh bodyguards assassinated prime minister Indira Gandhi.

The report by retired judge G. T. Nanavati said Tytler "very probably" organized anti-Sikh riots in New Delhi.

The report has been in the government's hands for months.

On Monday, the coalition government led by the Congress party said it would take no action against Tytler, now the minister in charge of non-resident Indian affairs, nor anyone else implicated in the report because there was no solid evidence against them.

Members of parliament belonging to the BJP and Akali parties were upset with that decision, and threatened to disrupt legislative business Tuesday.

Before that could happen, the speaker of the Lok Sabha adjourned proceedings for the day. The other house of parliament, the Rajya Sabha, followed suit soon after.

Meanwhile, about 300 relatives and friends of people who died in the 1984 violence staged a protest outside the seat of parliament.

They burned copies of the Nanavati report and carried signs that read "We want justice, not reports."

The Nanavati inquiry was the ninth investigation into the riots, which occurred while the Congress party was governing India.
