The Polit Bureau of the CPI(M) strongly condemns the serial bomb blasts in Patna yesterday which led to the death of five persons and injuries to scores of others.  These cowardly attacks once again highlight the urgent need to strengthen intelligence against terror attacks.  Governments at the Centre and the state have to coordinate to ensure that the real culprits are arrested.  The Polit Bureau calls upon the people of Bihar to maintain and strengthen their unity.
