People using Uber's app to call for a ride this weekend will see a peace symbol heading their way instead of a car. The ride share company has replaced the car symbol with a peace sign in the wake of "this week's terrible gun violence," according to a message you'll see when you open the smartphone app.

Uber also imposed a "moment of reflection" at midnight, blocking all ride requests for one minute.

"Our hearts go out to the victims of this week's terrible gun violence. As a show of solidarity to all affected, you'll see a peace sign in our app. As we move around our cities this weekend, let's take a moment to think about what we can do to help."

The app showed a swarm of peace symbols buzzing around Hollywood on a busy Friday night.

"At midnight, riders across the US will be unable to request a ride for one minute. We're sorry for the inconvenience. But we wanted to create a moment of reflection for the Uber community so that we can all think about what we ca do to help.

Uber will also be making donations to a number of social justice and anti-violence non-profits in Baton Rouge, Minneapolis and Dallas."
