Notice that protests in Saudi Arabia are called Shi`ite protests but protests in Syria are not called Sunni protests

"State media said the protesters were instigating riots and were detained Friday for setting tires on fire. Witnesses told Agence France-Presse that security forces had opened fire on the protesters, wounding several. The Saudi Press Agency reported that there were no casualties.  Though Saudi Arabia has not had mass protests on the same scale as other countries engulfed the Arab Spring, the Shiite protest movement has persisted in the east, growing more intense after a prominent Shiite cleric critical of the government was injured and arrested."
