Photos of the week: 9/4 - 9/11

This past week, the United States commemorated the 14 year anniversary of the September 11 terrorist attacks with somber events in New York, Pennsylvania, and beyond. We also saw headlines from the ongoing migrant crisis in Europe and the Middle East, and stories of severe weather from around the world.
