New Delhi: Piling up pressure on Pakistan, the US on Monday said an FBI team will take the evidence it has gathered in the Mumbai attacks to Islamabad and pursue the probe into the terror strike “to its conclusion”.

“The FBI will pursue the evidence gathered there (in Mumbai) and they will eventually take the evidence to Pakistan because under our law, if Americans are killed, the US itself has a duty to pursue all avenues to the bottom of it,” US ambassador in Delhi David C Mulford told reporters here.

“This is what the FBI is doing and will do in coming weeks and months,” he said.

Noting that the US has been rallying behind India on the issue of 26 November Mumbai attacks, Mulford said Washington will pursue the investigation into the carnage to its “conclusion.”

“The FBI has been in Mumbai since early December and has, I must say, been welcomed there. The level of cooperation offered to the FBI is very very significant and very much appreciated by the United States,” he said.

Asked about reports that Pakistan has rejected evidence given by the FBI, Mulford evaded a direct reply.

“I cannot comment on that because I don’t think the process is anyway completed,” he said.

Describing the cooperation offered by India to FBI as “very very positive experience”, he said some agency officials were still in Mumbai.
