In this Nov. 26, 2008 file photo, injured commuters and dead bodies lie at the Chatrapathi Sivaji Terminal railway station in Mumbai, India. Indian Prime Minister Manmohan Singh said Tuesday, Jan. 6, 2009, that he did not believe the November Mumbai attacks gunmen were acting alone, and Pakistani state agencies must have had a hand in the attacks. A ruthless exchange from a transcript of phone calls Indian authorities say they intercepted during the attack were part of a dossier of evidence New Delhi handed Pakistan this week that it says definitively proves that the siege was launched from across the border.

Pakistan has arrested at least two senior Lashkar leaders, but it was not clear whether either of them were on the phone with the gunmen during the attack.
Pakistani authorities are reviewing the evidence provided by India, but have dismissed Singh's claims and accused India of unnecessarily whipping up tensions between the nuclear-armed rivals that share a border.
Pakistani Information Minister Sherry Rehman did say Wednesday that the lone surviving gunman was a Pakistani citizen, after weeks of refusing to confirm India's claims on his nationality. Islamabad had previously said it could not find the surviving gunman, Ajmal Kasab, in its databases.
Predominantly Hindu India and Muslim Pakistan have fought three wars against each other since they gained independence in 1947. But both sides have said they do not want to go to war over Mumbai.
"We may be crazy in Pakistan, but not completely out of our minds," Pakistan's ISI agency chief Lt. Gen. Ahmed Shujaa Pasha told German news magazine Der Spiegel. "We know full well that terror is our enemy, not India."
