80 people were involved in the rescue of a beluga whale that was trapped in the river.
The 80 person operation included police officers and divers. French officials have not been able to figure out how the whale ended up in the river.
The secretary general of the Eure prefecture said it was a very technical rescue operation.
A crowd of people gathered on the banks of the river to watch the rescue.
French officials tried a number of things to increase the beluga's appetite, but nothing worked, according to the news outlet.
A whale was seen in the river on August 2.
A killer whale was found dead in the water. It became ill with a rare disease called mucormycosis.
Belugas are vulnerable to a number of stressors, including pollution, habitat degradation, and other types of human activity.
