WASHINGTON (Reuters) -There is a "low to medium" risk that Russia will invade Ukraine over the next few weeks, the top U.S. general in Europe said on Thursday, in the first such military assessment amid mounting concern about Russian troop movements toward Ukraine's borders.

Air Force General Tod Wolters declined to explain the intelligence driving his assessment, which does not suggest that the U.S. military expects a Russian invasion at this point, but he is not ruling one out or playing down the risk.
