Ukrainian President Volodymyr Zelenskiy has made a working trip to the Donetsk region and met with the Ukrainian troops close to hotly contested battle lines with Russia. The president's office said in a statement on its website that Zelenskiy made the December 6 visit to hand the soldiers state awards on Ukraine's Day of the Armed Forces. The statement said that Ukraine's east "today is the most difficult front." Russia has backed separatists in the region since 2014 and the region is the site of some of the heaviest fighting in Ukraine at the moment.
