NEW DELHI (AP) — “We have three foreigners, including women,” the gunman said into the phone. The response was brutally simple: “Kill them.” Gunshots then rang out inside the Mumbai hotel, followed by cheering that could be heard over the phone.

The ruthless exchange comes from a transcript of phone calls Indian authorities say they intercepted during the November Mumbai attacks. They 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.

Indian Prime Minister Manmohan Singh said Tuesday that he did not believe the gunmen were acting alone, and Pakistani state agencies must have had a hand in the attacks.

The dossier made no mention of any Pakistani officials or agencies.

Pakistani authorities are reviewing the evidence, but have dismissed Singh’s claims as “a propaganda offensive” designed “to whip up tensions” in the region.
