A Sunni Imam in Iran:

The internet is loaded with these kind of videos.
If your Farsi is weak, he says that Sahaba (r.a.) are openly insulted in government funded publications such as the Roznama Jam-e-Jam.
This is called religious persecution and there are many examples of these "miseries" of the Sunnis in Iran. They cannot defend their faith from the regime's vile propaganda.
The Baloch might be funded by foreign hands but they were recruited on the basis of legitimate grievances, not just money.
As he says in the video, if it was not for Hzt. Omar, no one in Iran would be Muslim, they should at least consider that before spewing hatred.
