(CNN) -- A massive rescue effort was under way Tuesday after a young child was found among the wreckage of a downed Yemeni jet off the coast of Comoros in the Indian Ocean.

"One child is alive and we hope to find more," Yemenia Airways chairman Capt. Abdulkhalek al-Kadi told CNN. The child has been taken to a hospital.

The French Navy is sending ships and a plane to help Yemeni authorities try to find any more survivors, he said.

Al-Kadi blamed the crash on bad weather, noting that there were "high seas and windy weather" at the time.

There was no indication of foul play behind the crash, the official in Yemen said.

In the wake of the Air France crash on June 1, United States accident investigators have been probing two recent failures of airspeed and altitude indications aboard Airbus A330s.
