A Comoran investigator says the black boxes from a Yemenia Airways flight that crashed into the Indian Ocean in June are damaged, AP reported.
Mohamed Ali Abdou says investigators are still trying to recover the information held in the flight's black boxes. Experts began examining the boxes from the Airbus 310 plane on Monday.
In a statement Friday, Ali Abdou says it is still unknown what caused the crash. Ali Abdou is assisting French experts from the BEA aviation accident agency. The French agency made no statement Friday.
The boxes were fished out of deep waters northwest of Grand Comoros island late last month by underwater robots.
Yemenia Flight 626 from Paris to Moroni, the capital of Comoros, plunged into the ocean June 30, killing 152 people. Only a teenage girl survived, plucked from the water after 13 hours.
Many crash victims had been from France's Comoran community.
