Condemning the Pune bomb blast, the CPI(M) today described the attack as "disturbing", saying it came despite prior warnings of a possible terror strike.

"Media reports on prior warnings concerning a possible terror attack in Pune are indeed disturbing as these attacks have taken place despite this. It is imperative in the

interest of the country's internal security that such lapses be identified and rectified urgently," it said in a statement.

The Left party asked the Centre to provide all necessary assistance to the Maharashtra government "to jointly identify the culprits who perpetrated this heinous attack and bring the guilty to book".

"The Polit Bureau of CPI(M) conveys its heartfelt condolences to the families of those who lost their lives in the attack and wishes those injured a speedy recovery," the statement said.
