RIYDH — A liberal activist sentenced to prison and flogging in Saudi Arabia will face a first round of lashes on Friday, rights watchdog Amnesty International said on Thursday.

Raif Badawi, who set up the “Free Saudi Liberals” website, was arrested in June 2012 and charged with offences ranging from cyber crime to disobeying his father and apostasy, or abandoning his faith.

He was sentenced to 10 years in prison, a fine of 1 million Saudi riyals ($266,666) and 1,000 lashes last year after prosecutors challenged an earlier sentence of seven years and 600 lashes as too lenient.

“Amnesty International has learned that the imprisoned Saudi Arabian activist Raif Badawi will be flogged in public after Friday prayers tomorrow in front of al-Jafali mosque in Jeddah,” the international rights group said in a statement.

It said Badawi would receive 50 lashes on Friday and the rest of the sentence would be carried out over a period of 50 weeks. His website included articles critical of senior Saudi religious figures and others from Muslim history.

Saudi Arabia’s legal code follows sharia Muslim law. Judges are trained as religious scholars and have broad scope to base verdicts and sentences on their own interpretation of religious texts.

Saudi Arabia on Wednesday condemned the killings of 12 people in an attack on a French satirical newspaper which had lampooned Islam. But it has also in the past called for an international law to criminalize insults to the world’s main religions.

The United States asked Saudi Arabian authorities on Thursday to cancel the sentence against Badawi.

“The United States government calls on Saudi authorities to cancel this brutal punishment and to review Badawi’s case and sentence,” State Department spokeswoman Jen Psaki said.
