Kiev police said they were investigating an attack by far-right activists on a Russian bank and the office of a Ukrainian politician who is a close friend of Russian President Vladimir Putin. Ukraine marked the third anniversary of the start of three months of protests that resulted in its Russian-backed former president being ousted in February 2014 as the former Soviet republic set on a pro-European Union course.
