A huge swarm of bees surrounded people at the Muslim Community Mosque in Phoenix, Arizona, in a terrifying moment caught on video.
At least 20 people were stung Friday, Phoenix Fire Department spokeswoman Ardell Deliz told ABC News.
One person -- a 24-year-old man -- was transported to the hospital in stable condition, Deliz said.
Firefighters rushed to the scene and sprayed the area with a foam that calms the insects, but Deliz said it took at least a few hours until a bee keeper could come remove them.
The Muslim Community Mosque did not immediately respond to a request for comment.
