Washington:Despite repeated declaration made by the Obama Administration that so far no evidence have been found which would ascertain Pakistani Government knowledge about the whereabouts of Osama bin Laden, a top Republican Senator on Monday said people connected with Pakistan military had information of Osama.

"It appears to me very logical that if Osama bin Laden was in that home for six years, a group of people there connected with the military knew about his whereabouts,” Senator Richard Lugar, said in an interview.

"Now the problem is that the divisions in the Pakistani government, between the ISI, the intelligence people, the military, the civilian, are very, very severe.  Not really clear how many persons in each of these categories were informed or how they entered the dialogue within Pakistan," said Lugar, Ranking Republican in the Senate Foreign Relations Committee.

At the same time, he argued that Pakistan is a critical factor in the war against terror simply because there are a lot of terrorists in their country.

"We are hopeful that they are secure, because the most awesome aspect of this would be that whether it is Taliban, al Qaeda or al Shabaab or somebody else get their hands on nuclear material because the Pakistanis are not secure in this respect, and then have an attack on the United States of a very different character," Lugar said.

"Now, that's a big difference from the thoughts that bin Laden might have been proposing attacks on American trains or bridges or this very possibly and a portfolio of circumstances. But Pakistan is a very critical country," he said.

"We are critical to them likewise, because their focus is India and will continue to be, unfortunately, for a long period of time. So, quite apart from Afghanistan, which they have perceived sometimes as a very useful place for them to deal with India or others, India is the big situation," Lugar said.
