JOPLIN, Mo. (AP) — A doctor has confirmed at least four people were killed at St. John's Regional Medical Center during the tornado that tore through the Missouri hospital.

Dr. Jim Roscoe said Monday he doesn't know if the victims there were patients or staff members. He compared the carnage to what he saw last year after the devastating earthquake in Haiti.

Authorities have said the tornado that tore a 6-mile path across southwestern Missouri killed at least 89 people.

Roscoe says some staff members who responded to the hospital after the storm already were injured, but worked through the night.

He says he arrived at the hospital soon after the tornado hit and it looked like it had been in a nuclear disaster.
