On Monday 6, August, 2001, at 17:50, [German] Ambassador Ischinger personally notified the President of the United States that information developed by the Bundesamt fur Verfassungsschutz [German domestic secret service] as well as the BND [Bundesnachrichtendienst, German foreign secret service] indicated that an attack by a radical Arab group partially based in Germany was to occur on 10-11 September, 2001. The President was at that time in residence at his farm in Texas. Our [the German’s] Ambassador was acting in direct response to instructions from Foreign Minister Fischer.
This information was developed from official surveillance of Arab extremist groups operating in the Federal Republic as well as from intercepted communications between the Embassy of Israel and the Israeli Foreign Ministry in Tel Aviv concerning this matter.
The information was “gratefully received” by the US President who stated at the time that he was also aware of the same pending assaults.
Subsequent to these attacks, the office of the US President, through the US Department of State, made an urgent request to the government of the Federal Republic of Germany that no reference whatsoever should be made to the official warnings given by Ambassador Ischinger.
In order to clarify the background of this matter, this Gesamtubersicht [overall survey] of the events leading to the assault was prepared, basing on extracts of reports from our [BND’s] foreign stations. Overall, it is evident that the American authorities were aware of the pending attacks. Why they did nothing, is explained in the following.
