We believe this has been mentioned here, yet I find it interesting to see the actual text before our very eyes.
Be forewarned that if you refuse to accept this WWII propaganda you will arrested in 16 European countries and Israel.
We see that "mass extermination by electrocutions & steam chambers" were 'factual, proven', and even endorsed by notables.

Preface from the site:
The 1943 The Black Book of Polish Jewry (BBPJ) statement on Treblinka assists us in tracing the evolution of our understanding of Treblinka from its earliest manifestations to the version presented by the State of Israel at the 1987-1988 Jerusalem trial of John Demjanjuk for crimes committed as Ivan the Terrible of Treblinka in 1942-1943.
Below are reproduced two descriptions of Treblinka that are found in the BBPJ:
a half-page statement by Dr. Ignacy Schwarzbart, member of the Polish National Council, made on 15-Nov-1942 (the Schwarzbart statement can be scrolled to below, or accessed by clicking on "Schwarzbart" within any links bar, as for example the one above) and all seven pages of Chapter 9 titled "Treblinka," which is identified as an "Official Report Submitted to the Polish Government" (accessible by scrolling down, or else clicking on any of the page numbers that follow "Official Report" within any links bar).
The BBPJ statement on Treblinka is particularly noteworthy for its seeming authority — the book's list of sponsors (click on "Sponsors") includes one first lady, one Nobel Laureate whose name has become synonymous with genius, three U.S. Congressmen, one U.S. Senator, one mayor of New York City, one U.S. Cabinet member, and other notables. Did ever a piece of Jewish-holocaust literature come more highly recommended than this one?
On top of such illustrious sponsors, the BBPJ also lists fifteen members of the Publication Committee (click on "Committee)," five of whom are accorded the title "Dr," and gives special acknowledgement to Abraham Goldberg, former chairman of the Administrative Council of the American Federation for Polish Jews, and following that on the same page lists nineteen contributing authors.
The number and prestige of the BBPJ's patrons and endorsers, together with its temporal proximity to the events described, leads us to expect an account of Treblinka that is superlatively accurate.
some incredible bits:
Dr. Ignacy Schwarzbart, member of the Polish National Council, stated in London on November 15, 1942:
"The methods applied in this mass extermination are, apart from executions, firing squads, electrocution and lethal gas-chambers. An electrocution station is installed at Belzec camp. Transports of settlers arrive at a siding, on the spot where the execution is to take place. The camp is policed by Ukrainians. The victims are ordered to strip naked ostensibly to have a bath and are then led to a barracks with a metal plate for floor. The door is then locked, electric current passes through the victims and their death is almost instantaneous. The bodies are loaded on the wagons and taken to a mass grave some distance from the camp. A large digging machine has been installed recently at Treblinka. It works ceaselessly, digging ditches, mass graves for Jews who are to meet their death there. The Ukrainian guards, witnesses of the mass murders, are allowed to keep the money stolen from the victims. These bestial murders sometimes take place in the presence of the local non-Jewish Polish population, who are helpless and overcome with horror with the sight of such inhuman violence."
The steam-room is adjacent to the building. Inside the steam-room there is a large vat which produces the steam. The hot steam comes into the chambers through pipes installed there, each having the prescribed number of vents. While this machinery of death is in action, the doors and valves are hermetically closed. The floor in the chambers has a terra-cotta inlay which becomes very slippery when water is poured over it. There is a well next to the steam-room, the only well in the whole area of Treblinka B.
In one of the first days of September, the chief of Treblinka thus murdered 500 young Jews by shooting them one after another with his gun; what is startling is that not one of this group of a few hundred men attempted to resist death. The execution lasted from 7:30 to 3 P.M.
The new death-house provides for the liquidation of 8,000 to 10,000 victims. If we consider that right now 2,000,000 murdered Jews, or the greater part of Polish Jewry, are already buried in the area of Treblinka, the disturbing question arises: for whom do the S.S.-men intend that new house of death; who are to utter their last breaths in that slaughter-house? Most probably the death-machine, once started, will not limit itself to murdering Jews. At present, the specter of death in steam chambers rises before the Polish population; there have already been some signs of it: according to a report of an eyewitness, the Germans exterminated a group of Poles in death-house No. 1, in the second half of August.
