The world's week in pictures

Occupy Wall Street protesters have marked the movement's first anniversary by clogging intersections in the New York financial district, leading to more than 180 arrests. Protesters roamed in groups of a few dozen each on Monday morning, chanting loudly about the ills of Wall Street. Of the few hundred protesters scattered throughout the city, more than 180 of them were arrested by early Monday evening, mostly on disorderly conduct charges.
