Meanwhile, Pentagon Press Secretary George Little said US chairman of the Joint Chiefs of Staff, Gen Martin E Dempsey, has spoken to Pakistani Army chief Gen Ashfaq Parvez Kayani. "My understanding is that Chairman Dempsey has been in contact with Gen Kayani.
It was a productive and professional conversation. I'm not going to get into the details. But that call has taken place," Little told reporters. The timing of the call was not divulged, except that it has taken place within recent days.
