An Indonesian diver died on a search for a passenger plane that crashed near the capital Jakarta on Saturday in an accident that killed 189 people on board.
Indonesia's search and rescue agency said Sichirul Anto, 48, died Friday while diving to search for the victims of the Leon Air jet that crashed into the sea.
"We are deeply saddened by the death of a hero with a humanitarian sense from the Indonesian team for rescue rescue," IAEA chief Mohamed Sioughe said in a press release.
Rescue spokesman Yousuf Latif told Reuters in a text message that the reason for Anto's death was not yet clear, adding that his family preferred not to perform an autopsy and demanded that his body be buried immediately.
Rescuers play crucial roles in retrieving human remains and cutting debris to see what happened to the nearly new Boeing 737 Max, which crashed into the sea early on Monday, 13 minutes after taking off from Jakarta.
As of Saturday, the number of bags of bodies taken from the site had reached 73, a few of them containing full bodies, but only four of the victims were identified.
Divers are searching the wreckage of the muddy seabed for the second black box, while investigators are trying to collect data from a partially damaged recording unit retrieved from the sunken wreckage on Thursday.
The JT 610 pilot asked permission to return to Jakarta and got it, but what happened afterwards and caused the plane to crash was still a mystery.
