The file, circulated by the Indian Foreign Ministry to several countries, included information from the interrogation of Mohammed Ajmal Kasab, the only Mumbai gunman captured alive, whom Indian officials maintain is a Pakistani national trained by terrorists reportedly with links with Pakistan's spy organization, The Times of London reported Monday.

The documentation also has details of terrorists' communications with their alleged handlers in Pakistan during the attacks, which began Nov. 26 and lasted for 60 hours, leading to more than 170 deaths in India's financial and entertainment hub.

"The material is linked to elements in Pakistan. It is our expectation that the government of Pakistan will promptly undertake further investigations," a spokesman for India's foreign ministry said.

During the weekend, Indian Home Minister Palaniappan Chidambaram said the dossier was "unanswerable," the British newspaper reported. "No one in his right mind can give answer to this evidence."

Chidambaram is expected to brief the White House about the contents of the report in Washington. The Times said the FBI may be asked to act on India's behalf to investigate matters related to the dossier in Pakistan.
