New Delhi: Prime Minister Manmohan Singh today said that terrorism and Left-wing extremism are two major challenges that the society is facing, Press Trust of India (PTI) reported.

He said that the Delhi High Court blast is a stark reminder that there cannot be any let up in the security set up. “We need to identify and address causes of radicalisation of our youth,” the prime minister said.

He also added that there is a need to ensure that the investigating agencies are free from bias of any kind.
