President Obama has ordered all US flags at half staff today in deference to the Boston Marathon bombing. The staff at New York's City Hall took the additional step of lowering the New York City flag and raising the flag for the city of Boston.

Deputy Mayor Howie Wolfson posted the photo on Twitter.


For good measure, here is what the flags of New York and Boston look like.
