Defense officials from Pakistan and India on Friday concluded two days of talks without reaching any agreement on a pullback of troops from the Siachen glacier, the world's highest battlefield, officials said. However, the two sides "agreed to continue talks in future," said a Pakistani official, who spoke on condition of anonymity. Indian Defense Secretary Ajai Vikram Singh told reporters only that the talks were held in a "cordial and positive atmosphere." His Pakistani counterpart, Tariq Waseem Ghazi, said there had been "forward movement" and the talks "helped us understand each other's position in a much better way." Pakistan's Foreign Ministry was to issue a statement later Friday, The Associated Press reported.
