Pakistan's foreign minister aims to sign a deal on nuclear security during a visit to India beginning Tuesday to underpin peace talks after a deadly attack on a cross-border train, an official said. Pakistan is hoping for progress in several fields during Khursheed Kasuri's visit, his spokesman Tasnim Aslam said. An agreement on nuclear risk reduction that has been discussed for several months "will hopefully be signed," she said. "There are a number of agreements that have been in the works for the last five, six months. The texts were finalized. Somehow, the Indians are not able to complete their procedures," she said. Pakistani and Indian leaders have condemned the train attack, which killed more than 60 people, most of them Pakistanis, as an attempt to derail the three-year-old peace process between the nuclear-armed neighbors.
