BOSTON — A magazine photo shoot for a cover marking the anniversary of the Boston Marathon bombings has drawn thousands of people, including survivors, emergency workers, well-wishers and city officials.

The Sports Illustrated cover shoot was held Saturday at the marathon finish line, where hundreds of people had gathered to watch runners finish the race when the twin explosions occurred on April 15, 2013. Three people were killed and 260 others injured.
