Huseyin Urkmez spent three months rowing the 1,500km (930 miles) from Hopa, near Turkey’s eastern border, to the port of Ortakoy in Istanbul, the Yesil Gazete website reports. He was greeted by the cheers of environmental activists after his mammoth journey, which he undertook in a standard rowing boat, the website says. Mr Urkmez describes his feat as a “symbolic demonstration” against nuclear power plants in the country, the Hurriyet Daily News website reports. “I wanted to draw attention to demands for a nuclear-free country only through my physical strength. If there is one thing as difficult as rowing against the current, it is challenging the government’s calculations,” he says.
