Saudi Arabia executed a prominent Shi'ite Muslim cleric and dozens of al Qaeda members on Saturday, signaling it would not tolerate attacks, whether by Sunni jihadists or minority Shi'ites, and stirring sectarian anger across the region.
Hundreds of Shi'ite Muslims marched through Qatif district of Saudi Arabia's Eastern Province in protest at the execution of cleric Nimr al-Nimr, an eyewitness said. They chanted "down with the Al Saud", the name of the ruling Saudi royal family.
Nimr, the most vocal critic of the ruling Al Saud among the Shi'ite minority, had come to be seen as a leader of the sect's younger activists, who rejected the quiet approach of older community leaders for failing to achieve equality with Sunnis.
Four, including Nimr, were Shi'ites accused of involvement in shooting policemen. But most of the 47 executed in the kingdom's biggest mass execution for decades were Sunnis convicted of al Qaeda attacks in Saudi Arabia a decade ago.
