Senior Congress leader Digvijaya Singh on Friday said involvement of Hindu outfits could not be ruled out in Wednesday’s blasts in Mumbai. In an interview, he said, "Nothing can be ruled out. We should allow the NIA and Anti-Terrorism Squad of Maharashtra to do their jobs. But we cannot rule out anything."

Mr. Digvijay Singh, who claims to be the first to have gone public about "Hindu terror" phenomenon, also sought to drag the BJP into investigations of previous blasts, saying the National Investigation Agency (NIA) probe into the 2007 murder of RSS activist Sunil Joshi might "establish" some BJP leaders' links. He offered to testify before the court on the involvement of RSS activists in terror-related activities. Singh has maintained that when he was Madhya Pradesh chief minister, he had come to know of the terror activities of RSS activists like Joshi. "If I am called (by the court), whatever information I have, I would love to share with everyone under oath."
