Washington: Agreeing to the US demands Pakistan on Tuesday granted White House access to the three widows of Osama bin Laden, who were detained soon after the killing of the al-Qaeda chief in his Abbottabad hideout last week.

The US investigating agencies would be given "direct access" to the three widows of bin Laden, meaning the US government agents will be able to interview them, and not just
submit questions, a news channel reported.

With this, Islamabad has met one of the major demands of the Obama Administration.

"A United States official said that American investigators would soon be allowed to interview bin Laden's three widows, now being held by Pakistani authorities," a newspaper reported.

While there was no official confirmation of this news from the White House, a TV channel said Pakistan will allow the US to question or take into custody the apparent wives of bin Laden only if their "country of origin has been asked for permission," according to a senior Pakistani intelligence source.

Earlier in the day, White House Press Secretary Jay Carney said the US is in consultation with the Pakistani government at many levels about access to bin Laden's wives, and some of the other materials that may have been collected by the Pakistanis after the US commando team left.

"We will continue those conversations. We believe that it is very important to maintain the cooperative relationship with Pakistan precisely because it's in our national security
interest to do so," he said.

On Sunday, Admiral Mike Mullen, Chairman of the Joint Chiefs of Staff, called Pakistani Army Chief Gen Ashfaq Parvez Kayani as part of the continued dialogue.

That's the highest level of contact between the two countries after US President Barack Obama called his Pakistani counterpart Asif Ali Zardari to inform him that Osama bin
Laden has been killed in a covert US operation.

Both the Pentagon and the State Department confirmed on Monday that neither Defense Secretary Robert gates nor Secretary of State Hillary Clinton have made any telephone calls to the Pakistani leadership after the last week's incident of killing bin Laden.
