Manhattan's Stonewall Inn, an iconic landmark of the gay rights movement, was the site of a vigil Monday for victims of a terror attack that killed 49 people and injured at least 50 more at a gay nightclub in Orlando, Florida, over the weekend.

The attack has sparked an outpouring of grief from the LGBT community and Americans as a whole.

"Even though it happened quite far away, it's something that affects everybody," said mourner Aaron Brodovcky.

Corey Fitzgerald said he mourns for the victims' families.

"My heart is broken for a lot of those people," he said. "I know so many parents lost kids."

Police in New York City stepped up security and deployed an additional 500 anti-terrorism officers in the wake of the attack.
