Donetsk is being shelled again, our news desk reports:
The separatist-held eastern Ukrainian city of Donetsk came under artillery and mortar fire again late on August 20.
AFP reported its journalists in Donetsk said shells were hitting the city center near the stadium where the soccer team Shakhtar usually plays.
The stadium was also one of the venues for the Euro 2012 soccer championship.
Russia's Interfax news agency cited the pro-Russian separatists' press service as reporting other areas of Donetsk were under artillery fire and that at least nine people had been killed and 13 wounded.
The attacks came after reports said 34 people were killed in fighting in the Donetsk area overnight.
More than 2,000 people have been killed in over four months of fighting between Ukrainian government forces and pro-Russian rebels in eastern Ukraine. (AFP and Interfax)
