The Riyadh regime executed Sheikh Nimr, along 46 others, on January 2.
The cleric was beheaded after Saudi authorities accused him of inciting his followers to violence, but human rights groups said he was executed for his political opposition to the Saudi regime.
His execution drew widespread condemnation worldwide.
He was charged with instigating unrest and undermining the kingdom’s security, making anti-government speeches and defending political prisoners. He had rejected all the charges as baseless.
In 2014, a Saudi court sentenced Sheikh Nimr to death, provoking global condemnations. In October 2015, a Saudi appeals court upheld the death sentence.
