Pakistani foreign minister Hina Rabbani Khar has said she would meet US Secretary of State Hillary Clinton in London on Thursday to discuss relations that have been damaged by a cross-border Nato air attack last November that killed 24 Pakistani soldiers. She was addressing joint press conference with British foreign secretary William Hague after their meeting in London on Tuesday evening. Pakistan closed Nato supply routes to Afghanistan after the air attack, which plunged relations between Pakistan and the United States to their lowest point in years.
