Leaders of various political outfits cut across party lines on Monday to condemn Sunday's serial bomb blasts in Bihar capital Patna.

Six of the bombs went off inside or near Patna's Gandhi Maidan, the venue for the BJP rally that was addressed by its prime ministerial candidate.

The remaining two blasts took place inside a public convenience complex at the Patna Railway Station.

In all, six persons lost their lives and over 83 others were injured by the blasts.

Commenting on the tragic incident, Communist Party of India leader S. Ramachandran Pillai said: "We condemn this incident. We do not believe in politics of violence. It is the responsibility of the ruling government to find out and bring out the culprits. None of the our workers are involved in this."

BJP president Rajnath Singh said: "There is no doubt that it is very unfortunate. I believe this incident happened because of terrorist activities. I would like to appreciate the people of Bihar for their patience. There is no doubt that this is a major security lapse. The Bihar Chief Minister called and expressed grief. He said that investigations are on, and assured that he will gather all the facts and details related to the incident in a day or two."

Senior Uttar Pradesh Congress leader  Rita Bahuguna Joshi said: "I totally condemn these (blasts). Strict action should be taken as soon as possible. It is a very serious matter."

Minister of State for Agriculture and senior Nationalist Congress Party  leader Tariq Anwar said: "First of all, I totally condemn this. To say that the government is involved in this will be totally wrong. The good thing is that the culprits have been caught."

Biju Janata Dal leader and Member of Parliament Jay Panda said: I strongly condemn this. It is an attack on democracy. I hope that action will be taken.'
