A prominent cyberactivist who was detained on the first anniversary of the 2011 uprising that sparked the Syrian civil war was secretly executed nearly two years ago, his widow said.
Bassel Khartabil Safadi, an open-source software developer who put his skills to use to promote free speech during the uprising, was put to death in October 2015, two and a half years after his arrest, Noura Gazi Safadi said.
That month, rumours had begun circulating that he had been sentenced to death after being transferred from the regime’s notorious Adra prison near Damascus to an unknown location.
