The Dnipro, Europe's fourth-longest river and a historic trading route, has become a key front since Ukrainian troops pushed Russian forces back over its banks in the country's south last year.

"They usually don't have enough time to aim" explains 'Vozhd', a Ukrainian sergeant, "so they are throwing everything in an area." IMAGES AND SOUNDBITES ++ COMPLEMENTS VIDI33ZT7ZC_EN
