KIEV (Reuters) - Ukrainian government forces are redeploying in preparation for a possible new offensive by pro-Russian separatists in eastern regions, Defense Minister Stepan Poltorak said on Wednesday.
He told a government meeting the rebels had received reinforcements despite a ceasefire that was agreed on Sept. 5 but has been repeatedly violated.
"We are repositioning our armed forces to respond to the actions of the (rebel) fighters," Poltorak said. "I see my main task is to prepare for military action."
A military spokesman said on Tuesday the rebels were beefing up their forces, including around the port city of Mariupol in the southeast, control of which would open up roads to territory in southern Ukraine.
Kiev says a column of tanks and truckloads of troops crossed into east Ukraine from Russia last Thursday and officials from the Organization for Security and Cooperation, a security watchdog, have spotted armored columns on the move.
Russia has denied supporting the rebels militarily in the conflict, in which more than 4,000 people have been killed since mid-April.
