Advocacy group Sikhs for Justice (SFJ), that led the protest, said a similar rally will also be held on November 2 in France where the Prime Minister will be attending the G-20 Summit.
"Singh's government has failed to prosecute the perpetrators (of the 1984 anti-Sikh riots) and instead is rewarding the killers of Sikhs with Cabinet positions," SFJ legal adviser Gurpatwant Pannun alleged in a statement.
The protest rally yesterday was organised by SFJ along with the support of management committees of tri-state area gurudwaras. The Sikh organisations have pledged to raise at international level the issue of "denial of justice" to the victims of 1984 riots, Pannun said.
