Karachi, July 21:

Two of the four London bombers visited Pakistan together in 2003 before making another trip about half a year ago, said a Pakistan intelligence official, adding that Shahzad Tanweer, 22, and Mohammad Sidique Khan, 30, who visited Pakistan from November 19, 2004, to February 8 this year, also came to Karachi in July 2003. The official said immigration records showed the two came in July 2003 but that searches of hotel records and interviews with leaders of madrassas, or Islamic schools, had so far failed to net any details.
