In the months following his return from Warsaw, Karski reported to the Polish, British and American governments on the situation in Poland, especially the Warsaw Ghetto and the Bełżec death camp, which he had visited secretly. (It is now believed that Karski had seen the Izbica Lubelska transit ghetto where Jews were held until they could be sent to Bełżec.) Newspaper accounts based on Karski's reports were published by "The New York Times" on November 25 and November 26, and "The Times" of London on December 7.
