NEW DELHI (AP) — India gave Pakistan the most detailed evidence yet that it says ties the militants who attacked Mumbai to “elements” in Pakistan — responding today to weeks of demands from Islamabad for proof that the siege was launched from across the border.

India has blamed the November attacks that killed 164 people on Pakistani-based militants, but Islamabad has denied the accusations and requested proof.

The evidence handed to the Pakistani High Commissioner in New Delhi today included material from the interrogation of the lone surviving gunman, details of conversations between the gunmen and their alleged handlers in Pakistan, recovered weapons, and data from satellite phones, according to a statement from India’s foreign ministry.

“This material is linked to elements in Pakistan,” the statement said. “It is our expectation that the government of Pakistan will promptly undertake further investigations in Pakistan and share the results with us so as to bring the perpetrators to justice.”

Pakistan’s Foreign Ministry spokesman Mohammed Sadiq said the authorities are reviewing the evidence and declined to comment further.
