protestUpdate, 6:30 pm: The protesters appear to have cleared away.

Protesters have amassed outside the 116th gates with the sign “Welcome Putin the Peacemaker.”  They are criticizing the U.S. and the Ukrainian government for their policies in Ukraine, and specifically the presence of Ukrainian President Petro Poroshenko at the World Leaders Forum.

They’ve led numerous chants against the United States in general and Poroshenko in particular, including, “Hey hey, ho ho, Poroshenko’s got to go,” “Crimea is Russia,” and “The capitalist police protect Nazis.”  The protestors’ signs accuse Obama and Ukrainian President Petro Poroshenko of “war crimes” and urge the White House to “stop funding Neo-Nazis in Ukraine.”

One of the protesters attacked a policeman, and was tackled and arrested. (See video below.)

NYPD is controlling the protest and directing students away from College Walk.
