Among those killed was noted Shi'ite Muslim cleric Nimr al-Nimr, the nation's Interior Ministry said in a statement.

The nation detained thousands of militant Islamists after a series of al Qaeda attacks from 2003-06 that killed hundreds, and has convicted hundreds of them.
However, it also detained hundreds of members of its Shi'ite minority after protests from 2011-13, during which several policemen were killed in shooting and petrol bomb attacks.
Several of the Shi'ites have been sentenced to death.
Saudi Arabia's main regional rival, Shi'ite Iran, has warned that executing Nimr "would cost Saudi Arabia dearly".

Saudi Grand Mufti Sheikh Abdulaziz Al al-Sheikh appeared on television soon after to describe the executions as just.
