MOSCOW – A spokesman for Ukraine's military operation against separatist rebels in the country's east says six soldiers have been killed over the past day.
The statement by Oleksander Motuzyanik on Sunday comes amid increasing concern about a recent escalation in fighting between Ukrainian forces and Russia-backed rebels. On Tuesday, Ukraine reported seven of its soldiers had been killed.
The Donetsk People's Republic, one of two self-proclaimed separatist republics in the east, claimed Sunday that Ukrainian forces had shelled positions there more than 600 times in the past day, the Russian news agency Tass reported.
The United Nations says more than 9,400 people have been killed since the conflict broke out in April 2014.
