Commie heartache.

(AFP) — Two peaceful demonstrations were held in Chile Sunday protesting the upcoming visit of President Barack Obama and rejecting a recently signed US-Chilean nuclear agreement.

Some 2,000 people marched in downtown Santiago against Obama’s visit on Monday in an event organized by the environmental group Greenpeace.

The protesters were angry that Chile signed a nuclear energy agreement on Friday with the United States despite Japan’s huge atomic crisis.

Some 300 people, including influential union leaders and members of Chile’s Communist Party, earlier marched in the downtown Plaza de Armas carrying banners that read “Obama Persona No Grata” and “Gringos Go Home.”

“This demonstration is to reject Barack Obama’s militaristic policies,” protest organizer Ricardo Sole told AFP.
