BJP on Saturday demanded a reply from Prime Minister Manmohan Singh on the reported statement by Assam chief minister Tarun Gogoi about delay in deploying the army to help curb violence.
The party also accused Congress of being responsible for the ethnic violence.
"The Prime Minister has gone to Assam and described the Kokrajhar incidents as a 'blot' on the nation...We demand a reply from Manmohan Singh that Tarun Gogoi, who is their chief minister, has accused the Centre of not sending timely help and forces," BJP spokesman Shahnawaz Hussain said.
Terming the situation in Assam still tense and asking the government to take immediate steps to improve the situation there, Hussain said adding "who is responsible for the Kokrajhar violence? Congress cannot be absolved of its responsibilities."
Charging he Congress-led government at the centre and Assam with being responsible for the violence, the BJP leader said "the situation in Assam has not come about in a day. It was happening for quite some time. The Manmohan Singh government and Tarun Gogoi government have failed completely."
