DONETSK Ukraine/MOSCOW (Reuters) - Russian President Vladimir Putin called on pro-Moscow separatists in Ukraine to postpone a vote on secession just five days before it was to be held, potentially pulling Ukraine back from the brink of violent dismemberment.
It was the first sign the Kremlin leader has given that he would not endorse a referendum planned for Sunday by pro-Russian rebels seeking independence for two provinces in the east, and Russian analysts said they believed the rebels would heed Putin's call to put off the vote.
