US officials 145;expose146; Pak Qaeda suspect

8216;8216;He was cooperating with interrogators on Sunday and Monday and sent e-mails on both days,8217;8217; said the source. Khan was moved to a new location on Monday evening, he said.

US officials revealed Khan8217;s name in anonymous briefings with journalists after New York and Washington were put on high alert for a possible Al Qaeda attack. The officials said the alert was prompted after Khan8217;s capture in Pakistan last month yielded documents, computers, surveillance reports and sketches. A string of arrests in Britain this week also resulted from Khan8217;s detention.

The source said Khan had intended to hack into both the FBI8217;s website and a British official website to destroy them.

Interior Minister Faisal Saleh Hayat on Friday drew a veil over Khan8217;s contribution to the breakthroughs against Al Qaeda in Pakistan, Britain and the US. 8216;8216;This is a sensitive subject. We must exercise extreme caution in coming out with such names and such information,8217;8217; he said.
