From Iran's FARS:
Large numbers of Iranian students staged a rally in front of the UN office in Tehran to protest at the massacre of peaceful protestors in Bahrain and other Islamic countries in the region.
Protestors voiced their support for Muslims in Bahrain and other Islamic countries and underlined that they will continue their support for the oppressed people in those states.
The students chanted various slogans such as 'Allaho Akbar', 'Down with the USA', 'Down with the Zionist regime', 'Down with Zionist Saudis', 'Down with American-style Islam' and 'Saudi commits crimes and the UN backs it' to voice their support for people in Bahrain and other Islamic countries.
The students urged the Iranian government to dispatch voluntary forces to Bahrain and in other Islamic states.
Financial Times (behind paywall) reports
Iranian clerics and religious students abandoned their classes and staged protests inside their seminaries to show solidarity with Bahrain’s mainly Shia opposition and to denounce last month’s Saudi military intervention in the archipelago.
At gatherings in the holy cities of Qom and Mashhad, which were attended by senior clerics and aired live on state television on Wednesday, protesters shouted, “Death to Zionist Saudis” and, “The wicked Bahraini ruler is an enemy to Prophet [Mohammed]."
Of course, we already knew that Saudi Arabia was Zionist.
Which is not surprising, since many Muslims know that the Saudis themselves are Jews.
Those Zionists are everywhere!
