The body of a kidnapped Ukrainian journalist who played an active role in protests that led to president Viktor Yanukovych's removal in February has been found in a forest 60 miles outside the capital, Kiev.

Cherkassk province prosecutors said Vasily Sergiyenko was abducted in his home city of Korsun-Shevchenkivskyi on Friday evening, and later murdered.

The nationalist Svoboda party, of which Mr Sergiyenko was a member, said the reporter was found with stab wounds and signs he had been beaten about the head and knees.

The party, whose leader Oleh Tyahnybok is running in the May 25 presidential election, said Mr Sergiyenko and other Svoboda representatives had received threats over the past week.
