Excerpt from the Riegner Telegraph

Have received through foreign office following message from Riegner Geneva Stop.

Received alarming report stating that in the Fuehrer's Headquarters, a plan has been discussed and is under consideration according to which all Jews in countries occupied or controlled by Germany numbering 3½ to 4 millions should, after deportation and concentration in the East, be at one blow exterminated, in order to resolve, once and for all the Jewish question in Europe.
