MUMBAI, Dec. 5  -- The minister in charge of Indian law enforcement acknowledged Friday that failures in intelligence and security made the Mumbai terrorist attack possible.

Home Minister P. Chidambaram also said that the government is considering setting up a national investigative agency modeled on the FBI in the United States.

"I agree that there has been a failure on the part of the security forces, but this attack will help the Government be more determined in combating terrorism," Chidambaram said in a news conference at police headquarters in Mumbai.

Chidambaram suggested to reporters that investigators have found evidence of involvement by some members of the Pakistani Inter Services Agency.

"There is ample evidence to link the attack to organizations or entities which have been responsible for terror attacks in the past," he said. "At this stage, it would not be correct to name any organization but you can draw conclusions." (UPI)
