"Eradication of terrorism from the country is only possible if we remain alert", Raja, a sitting Rajya Sabha MP said in Jaipur after visiting those injured in the blasts in a hospital.

"No special law is required to counter the menace", the left leader said.

Raja's comments follow the demand made by Rajasthan Chief Minister Vasundhara Raje for a law on the lines of defunct POTA to deal with terrorism.

She has also regretted that a bill on organised crime passed by the state Vidhan Sabha in 2006 was still awaiting the President's consent.

CPI MP Tapan Sen, who accompanied Raja, was of the view that authorities should take care that innocents were not harassed during their hunt for suspected militants belonging to Bangladesh-based Harkat-ul Jihadi Islami (HuJI).

While advocating stern action against the terrorists involved in the blasts, Sen said, “Every Bangla speaking person is not a Bangladeshi, he could be from West Bengal too".
