Saudi Arabia said Saturday it has executed 47 prisoners, including reformist Shiite cleric and activist Sheikh Nimr al-Nimr.
Al-Nimr was a central figure in Shiite protests that erupted in 2011 as part of the Arab Spring, and carrying out his execution may spark new unrest among the OPEC powerhouse’s Shiite minority.
The cleric’s name was among a list of the 47 carried by the state-run Saudi Press Agency. It cited the Interior Ministry for the information. Saudi state television also reported the executions.

Saudi Arabia carried out at least 157 executions in 2015, with beheadings reaching their highest level in the kingdom in two decades, according to several advocacy groups that monitor the death penalty worldwide.
His 17-year-old nephew was sentenced to crucifixion earlier this year but was not among those put to death this time.
Maya Foa, a spokeswoman for rights group Reprieve, said 4 of the 47 executed were political prisoners.
“Last year saw Saudi Arabia execute over 150 people, many of them for non-violent offences,” she said. “This appalling news suggests 2016 could be even worse. Alarmingly, the Saudi Government is continuing to target those who have called for domestic reform in the kingdom.
