Pope Francis has preached against religious persecution of all types, all times, by whomsoever made. He knows that Muslims are being persecuted too. He does not distinguish between the faiths of those who are being persecuted. Why for example, do you think that many of the Syrian refugees who have been brought directly to the Vatican have been Muslims?
I see no reason to spend time looking for 'citations' (plural, indeed!) for you. Instead, I suggest you do some research yourself, rather than leaping to your conclusion that the Pope has only now mentioned that Muslims are being persecuted.
As for Wesolowski (this being, I suppose, your tenuous link with this article, and with St Bakhita), I don't know of any evidence that Pope Francis was 'enabling' Wesolowski. Quite the contrary, in fact. Francis acted against Wesolowski - dismissing him from his posts, and bringing him to Rome for investigation and trial. It is a shame that it never got to trail. Was that Francis's doing too?
