Wednesday's shooting in the eastern German city of Halle outside of a synagogue was livestreamed on Amazon's Twitch service, the company confirmed to CNBC. The video was 35 minutes long. Two people were killed in the attack, German police said earlier in the day.

"We are shocked and saddened by the tragedy that took place in Germany today, and our deepest condolences go out to all those affected," a Twitch spokesperson said. "Twitch has a zero-tolerance policy against hateful conduct, and any act of violence is taken extremely seriously. We are working with urgency to remove this content and permanently suspend any accounts found to be posting or reposting content of this abhorrent act."
