Azerbaijan on Tuesday sentenced award-winning investigative journalist and anti-graft campaigner Khadija Ismayilova to seven and a half years in jail on corruption charges she denounced as trumped-up, her lawyer said.

"Baku's Court for Serious Crimes sentenced Khadija Ismayilova to seven and a half years in prison for economic crimes, including illegal entrepreneurship and tax evasion," her lawyer Fariz Namazly told AFP.
