Fresh volleys of artillery fire were heard across many parts of the separatist stronghold of Donetsk in eastern Ukraine on Sunday, a Ukrainian government statement said, after Kiev warned again of rebel preparations for a fresh offensive.
Ukrainian government forces have no intention of renouncing a ceasefire in the separatist-held east of the country, a military spokesman said on Thursday.
NATO is concerned about convoys of trucks taking artillery and supplies into east Ukraine from Russia, and wants to see international borders respected, the supreme allied commander said on Tuesday.
East Ukraine's rebel stronghold Donetsk was pummeled on Sunday by the heaviest shelling in a month, and the OSCE said it spotted an armored column of troops without insignia in rebel territory that Kiev said proved Moscow had sent reinforcements.
