"The assassination of Rajiv Gandhi was an attack on the unity and integrity of India. This matter has to be taken seriously. All political parties should rise above petty politics," he said.
Meanwhile, the BJP said that it sympathized with the Congress party on the issue but the party should have decided on the mercy petitions of the accused while it could.
"Why did the government sit on their mercy petition? Why couldn't they take a decision?" asked BJP vice president Mukhtar Abbas Naqvi.
