The first time Indian security agencies gave this information to the US authorities was in mid-2007, soon after a Taliban meeting in Peshawar which was attended by Osamas No.2 Ayman al-Zawahiri. According to the information gathered by Indian intelligence operatives, this meeting was also attended by top leaders of Haqqani network and at least two ISI officials.
Days after the meeting, Zawahiri visited Islamabad as per the information available with Indian authorities and this formed the basis of Indias first input to the US about Osamas hideout. “The urgency with which Zawahiri visited Islamabad or the area in its vicinity suggested that he was there for some purpose. We told them about Zawahiri visiting Islamabad and we also told them that we believed Osama may not be hiding in caves but in a highly urbanized area somewhere near Islamabad. Of course, nobody had spotted him and it was a conclusion we drew on the basis of the information we got,” said a top intelligence official involved in processing the information.
