From the New York Times online:
Mr. Bush and Mr. Musharraf made their remarks on the serene lawn of Aiwan-e-Sadr, with ducks splashing in a flower-filled pool in the background, as the capital around them remained in an effective 24-hour lockdown. Security was intense for the first visit of an American president in six years, and the first by Mr. Bush, who was in essence traveling to Mr. bin Laden’s backyard two days after a suicide bombing attack in the southern city of Karachi left four dead, including an American Embassy employee.
Mr. Musharraf said he had expressed Pakistan’s deepest regrets in his talks with Mr. Bush about the bombing, which he said was very viciously timed to spoil Mr. Bush’s visit. Mr. Bush said that he sent his condolences to the family of David Foy, the embassy employee killed in the attack, as well as to the families of the Pakistanis who died.
