Pakistani President Pervez Musharraf has offered to construct a security fence to deter movement of militants across the border into Afghanistan -- apparently in an effort to counter persistent criticism that he is not doing enough to combat terrorism. According to Pakistan's foreign minister, General Musharraf made the offer at a meeting with Secretary of State Condoleezza Rice on the sidelines of the United Nations in New York. Foreign Minister Khurshid Kasuri told reporters Pakistan does not want to hear any more that it is not doing enough. He did not say if Ms. Rice expressed support for the idea, but noted she was "very appreciative" of Pakistan's desire to help keep militants from crossing into Afghanistan. The head of the al-Qaida terror network, Osama bin Laden is thought to be hiding in that border region.
