New Delhi, Sep 30 (IANS): India Friday said it was not surprised that the US has "lately discovered" the terror links of Pakistan's Inter-Services Intelligence (ISI) spy agency.

Home Minister P. Chidambaram told reporters here that India had always known about the ISI's dark side and the remarks of a top American military commander about the agency did not surprise him.

"We are not surprised at all that the US has lately discovered ISI's links with global terror groups. We have always know this," Chidambaram said at his monthly press conference here.

US Joint Chiefs of Staff Chairman Admiral Mike Mullen, at a Congressional hearing last week, had said the "virulent" Haqqani network is a "veritable arm" of the ISI. He had reiterated this during a radio interview earlier this week.

"The ISI specifically has enough support for the Haqqanis in terms of financial support, logistic support and actually, sort of free passage in the safe haven and those links are part of what enable the Haqqanis to carry out their mission," Mullen told the popular National Public Radio (NPR).

The White House and Pentagon have, however, sought to distance themselves from his remarks.
