DONETSK, Ukraine (Reuters) - The new governor of the eastern Ukrainian region of Donetsk on Friday said Russians were behind violent clashes between rival demonstrators in which one man was killed, and accused Moscow of distorting the truth in its account of what happened.
Russia warned it could move in to protect compatriots - a similar justification as used in last week's military takeover of Crimea. And Ukraine's acting president raised the alarm over a Russian troop build-up on the eastern border that has fuelled fears in Kiev of a broader invasion by its former Soviet ruler.
