BISMARCK, N.D. (AP) -- An explosion at a newly drilled oil well in western North Dakota killed two workers and severely injured two others, officials said.
The fatal fire was one of two oil field-related blazes reported in the Williston area Wednesday. The other was much smaller and no one was hurt. Both happened in a part of the state that is experiencing what many are calling the largest oil boom in recent North American history.
