Ukraine rebels claim being shelled again

The Kremlin said on Thursday it was "deeply concerned" with the flare-up in Ukraine and was watching the situation closely.

According to the Interfax report, the self-proclaimed Donetsk People's Republic said the shelling targeted the Petrivske village in the breakaway region at 5.30am on Friday.

Kyiv and the pro-Russian separatists have been at war for eight years and the ceasefire between the sides is routinely violated, but the intensity of fighting increased notably this week.
