Protesters clash with riot police during a demonstration against President Barack Obama’s visit to Athens on Nov. 15, 2016.
Greek police say about 3,000 anarchists, left-wing activists and students marched through central Athens.
There’s a strong anti-American tradition among Greek left-wingers, who still resent U.S. support for Greece’s 1967-74 military dictatorship.
During the trip, the outgoing president has repeatedly referred to the anger that lately brought success to populist movements in Europe and the United States, such as the Brexit referendum and Trump’s shock victory last week.
In comments Tuesday Obama cautioned the world must guard against “a rise in a crude sort of nationalism or ethnic identity or tribalism that is built around an ‘us’ and a ‘them.’”
