Ukrainian soccer champion Shakhtar Donetsk's stadium has been damaged by shelling during the conflict between government troops and pro-Russian separatists.

Club chief executive Sergei Palkin said two shells struck the stadium complex early Saturday morning, one damaging the arena itself and another striking its electricity substation.

Shakhtar published photos showing debris strewn around an entrance to the stadium, but said there were "no casualties among the stadium staff."

Shakhtar's home city of Donetsk is the largest city controlled by pro-Russian rebels. Fighting around the city has become more intense in recent weeks.

Shakhtar is playing its home games this season in the western Ukrainian city of Lviv due to the conflict.

In May, Donetsk's ice hockey arena was looted and burned.
