People around the globe held vigils for those killed and wounded Sunday in a mass shooting at an Orlando gay nightclub.

Described as the worst mass shooting in American history, 50 people died and 53 were injured.

People gathered to remember the victims in several U.S. cities, including New York, Chicago and Washington, D.C.

“This is just another example of how gun violence affects everyone in the country at some point in time,” Eddie Johnson, Chicago's chief of police, said during a vigil held in Chicago. “So we're here to support not only Orlando, but to support the community here and let you all know that we'll always be here for you.”

Prayer vigils were also held in Sydney, Seoul and Berlin, the AP reported.

“We've been very shocked about this terrible act and now we want to show our solidarity with the victims and their relatives,” Joerg Steinert of the Lesbian & Gay Association told the AP. “We want to make clear that we live in an open and free society and we will not be intimidated.”

Israeli Prime Minister Benjamin Netanyahu called the shooting “horrible.”

“In the name of the Israeli government and people, I want to once again express condolences to the American people and the families in an especially difficult and tragic hour,” he said.
