There are a few prayer houses (Namaz Khaneh, there is NOT a single visible Sunni Mosque) in Tehran (yet the devilish Iranian Shia media such as PRESS TV and other notorious liars claim there are Mosques for Sunnis in Tehran!) but even they are being raided and the Sunnis of Tehran (LARGEST religious minority of Tehran) are harrassed on a regular basis. There are over 40 (!) churches in Tehran, over twenty Synagoges, Zoroastrian (Majoos) temples (even Zoroastrian highschools!) and even a SIKH temple in Tehran. Jews have their OWN private hospitals, yet Sunnis are not allowed to own a SINGLE proper visible Sunni Mosque (the Shia authorities are scared to death of authentic Islam, they know it will attract the masses who – particularly in Shia cities – know nothing about Sunni Islam except what they are being told by the biased and secterian Shia clergy), Sunnis are not even allowed to own a bookshop, let alone a Mosque! Who is more oppressive? Washington, Moscow and Israel or the secterian Iranian Shia Republic of Iran? Keep in mind, no matter how unjust the former are, at least they allow their citizens to build Mosques (for Shias and Sunnis alike!), whereas Tehran is the ONLY major capital of the world where Sunnis can’t perform their religious rights behind one of their Imams i.e. they don’t own a SINGLE Mosque!
