KIEV, Aug 10 (Reuters) - A Ukrainian military spokesman on Sunday dismissed a call for a ceasefire by a separatist leader, saying this could only take place once rebels had put down their weapons and surrendered.
A senior leader in the self-proclaimed Donetsk People's republic in eastern Ukraine said on Saturday that the rebels were ready for a truce with government forces to allow humanitarian aid to be brought in.
Replying to a journalist's question on Sunday, military spokesman Andriy Lysenko said: "If there is this initiative it should be carried out by practical means and not words - by raising white flags and by putting down guns.
"We have not seen these practical steps yet," he said. (Reporting by Natalia Zinets; Writing by Richard Balmforth; Editing by Catherine Evans)
