The Council of Europe on Monday awarded its top rights prize to jailed Turkish philanthropist Osman Kavala, who has come under repeated attack from President Recep Tayyip Erdogan.The Council of Europe said Kavala had supported several civil society organisations since the 1990s and that the moves against him were aimed at gagging critics and stifling dissent.Kavala said last month that the decision by the top appeals court to uphold his life sentence disregarded law and human life.
