Saudi Arabia has beheaded a man accused of taking part in anti-government riots when he was a teenager. Tuesday’s execution of 26-year-old Mustafa Hashem al-Darwish came despite international outcry. He was imprisoned in 2015 for allegedly participating in a protest of minority Shia Muslim youth demanding jobs and an end to discrimination at the height of the Arab Spring in 2011 and 2012. Al-Darwish was just 17 or 18 years old at the time of the uprising. Human rights groups say Saudi Arabia has carried out at least 26 executions this year.
