The newest season of France’s version of "Survivor" (called “Koh-Lanta”) has been canceled after a contestant died of a heart attack on the first day of filming.

The hit show, readying for its 13th season, had cast members and crew filming in Cambodia when Gerald Babin, 25, went into cardiac arrest after a tug-of-war competition. A staff physician  suffered cramping during the challenge and was treated by on the set. When Babin failed to show improvement, he was taken to a nearby hospital where he suffered “a series of cardiac arrests”.

“It is not really a question about whether to cancel the season,” said a spokesperson for the French television network. “Everyone is being flown back to France.”

The production company said that all contestants cleared a medical exam before filming began.

"Koh-lanta", which has filmed in remote regions of Thailand, Panama and Cambodia, among others, is France's longest running reality series. There's no word from the show's producers when or if "Koh-lanta" will return to the air.
