NEW ORLEANS (AP) — Doctors say one of four men burned in an oil platform explosion and fire has improved to fair condition. But two remain in critical condition and one in serious condition.

A news release on the Baton Rouge General Medical Center’s website says 50-year-old Wilberto Ilagan told Dr. Jeffrey Littleton that he wanted his family and country to know that he’s alive — and, though he’s burned, his heart and lungs are healthy.

The Advocate reports that Littleton told a news conference the other men’s names are being withheld because their conditions are more serious.

Two workers died at the rig; the body of one has been recovered, while crews continue to search for the other. Neither has been identified.

Authorities have said all the workers are from the Philippines.
