Patna, Nov 2 (Agencies) : Launching a blistering attack on Congress, Prime Minister Narendra Modi on Monday said that the Sonia Gandhi-led party had no right to lecture the BJP and his government over tolerance at a time when the nation is observing 31st anniversary of 1984 anti-Sikh riots.

Addressing a public gathering in Purnea ahead of the fifth and final phase of Bihar Assembly election, Modi said," Do you remember what happened on November 2, 1984 in Delhi? Sikhs were killed. Congress leaders were blamed for it and how ironic is it that the same party is lecturing us on tolerance."

"Aaj bhi un Sikh parivaron ke aansoo nhi ponchhe gye hain (Sikh families are awaiting justice even now)," Modi said in his last push before campaigning for the final phase ends on Tuesday.

This is for the first time that Modi has targeted the Congress, which is a part of the grand alliance comprising of Lalu Yadav's RJD and JD(U), over 1984 riots while canvassing for Bihar polls. Political analysts believe that Modi's outburst against Congress has to do with the Opposition's continuous attack on the BJP over the issue of 'tolerance'. While Modi has been talking about development being his only agenda, the Opposition has left no stones unturned to targeted him over incidents like Dadri and beef controversy.

Modi's remark comes ahead of Congress president scheduled meeting with President Pranab Mukherjee where she is likely to raise the issue of rising intolerance in the country.

According to Congress insiders, Sonia along with son and party vice-president Rahul Gandhi and senior party leaders will meet Pranab Mukherjee in the evening to discuss the "current political situation".
