New York: A US court issued summons to the Congress party to reply charges of 'conspiring, aiding, abetting and orchestrating organised attacks on the Sikh population in November 1984.'

The US District Court for the Southern District of New York issued the summons on Tuesday against a law suit filed by Sikhs for Justice (SFJ), a US based community group along with several Sikh survivors of the 1984 attacks.

According to SFJ legal advisor Gurpatwant Singh Pannun, the complaint against Congress alleges that in November 1984 the "organised killing" of Sikhs took place only in states where Congress was ruling.

"The gravity, scale and specially the organized nature of these attacks were concealed by the Indian governments," Pannun said.

These attacks were neither "riots" nor were they confined to Delhi alone. In fact, Sikhs were attacked in 18 states and more than 100 cities of India in an identical manner and the attackers were led by Congress (I) leaders, the complaint alleged.

The Congress party, in power then and now, committed the crime of genocide against Sikhs as defined in Article 2 of UN Convention on the Prevention and Punishment of the Crime of Genocide, 1948, it said.

The government of India, by painting the attacks on Sikhs in November 1984 as "riots" instead of "genocide" and by failing to punish the leaders of Congress (I), violated its duties under Article 1 the Genocide Convention, Pannun said.

The SFJ complaint also refers to the February 2011 discovery of "mass grave" of Sikhs who were killed in November 1984 in Haryana.

According to the record a total of 3,296 Sikhs were killed while a total of 35,535 claims for deaths and injuries were received throughout India, he said.
