The United States gave heads up to India, besides Afghanistan and Pakistan, on the leak of more than 90,000 classified documents pertaining to the war against terrorism.
The documents released by Wikileaks, which the Obama Administration has termed as a federal violation, further strengthens what top Indian officials have been saying for quite some time now that ISI has links with Al Qaeda, Taliban and other extremist organizations.
"We also gave a heads-up to India," State Department spokesman P J Crowley told reporters at his daily news briefing on Monday. He said the governments of Afghanistan and Pakistan were also informed about the upcoming documents.
Both the White House and the State Department acknowledged that they are concerned about the links between ISI and the extremist elements.
"From the standpoint of India, India clearly, you know, wants to see that Pakistan is taking steps to bring to justice those people that threaten neighbouring states," Crowley said.
"So, clearly, as we've said many, many times, if Pakistan wants to convince India that it has made this kind of fundamental change, bringing to justice those who are responsible for the Mumbai attack would be a very, very constructive and important step," he said in response to a question.
Noting that combating terrorism is an element of its relationship with India, likewise with Pakistan and Afghanistan, he said the US strongly believes that the proof is in what people do, not what people say.
"As we've highlighted here, the fact that Pakistan is taking aggressive action against insurgents within its own borders reflects their understanding that now insurgents threaten Pakistan itself," Crowley said.
The spokesman said the US continues to have conversations with Pakistan on bringing to justice those responsible for the Mumbai attack.
