WASHINGTON, Aug 9 (Reuters) - Russia has used "disproportionate" force in the South Ossetia conflict with Georgia and must immediately withdraw its troops and agree to a ceasefire with Tbilisi, a senior U.S. official said on Saturday. "The response has been far disproportionate from whatever threat Russia was citing," a senior U.S. official told reporters in a conference call. "We are calling for an immediate cease-fire and a stand down of all troops," he added. (Reporting by Sue Pleming; editing by Patricia Zengerle)
