A swarm of bees has killed a man in Arizona and sent another to hospital.
They were part of a group of four cutting grass and weeding for the owner of the house, a 90-year-old man who was not stung, news reports said.
According to the Arizona Republic, one worker had collapsed and was in respiratory arrest by the time then emergency medical personnel arrived at the scene.
He died at the hospital. The other was stung about 100 times, the newspaper said.
