PHILADELPHIA (AP) — Philadelphia police shot two dogs that were attacking a man on a city street, killing at least one of the animals.

The attack occurred at 4:40 a.m. Monday.

The injured man suffered serious undisclosed injuries and was hospitalized in critical condition. His name has not been released.

It wasn’t clear who owned the dogs.
