Local officials in eastern Ukraine say two people were killed in late-night shelling in the besieged city of Donetsk.

The Donetsk city council said in a statement posted on its website that two people were killed late Thursday. In a separate statement, local authorities said explosions could be heard throughout the city overnight, but they gave no further details about casualties or damage.

Ukrainian troops routed the pro-Russian insurgents from smaller towns in the region earlier this month and have now encircled Donetsk, where fighting has crept closer to the city center. The city council said it was working to keep transport services running and to repair gas networks in apartment buildings.
