Pope Francis touched upon the Armenian Genocide during his Sunday mess in Turin, during which he accused the world powers of failing to act.

Pope said they failed to act when  Jews, Christians, homosexuals and others were being transported to death camp in Europe during the World War II, Associated Press reported.

“The great powers had photographs of the railway routes that the trains took to Auschwitz to kill Jews, Christians, homosexuals, everybody,” Francis said, citing the death camp in Poland, and asked: “Why didn't they bomb" those railroad routes?”

He also denounced deaths in the Stalin camps in Russia.

Speaking about the 1915 events, Pope said it was a “great tragedy of Armenia.”

“In the last century, so many, millions, (of Armenians) died. But where were the great powers then? They were looking the other way,.”His Holiness added.
