The cockpit voice recorder recovered from flight MH17 is in good condition, the UN civil aviation body said.
The Montreal-based International Civil Aviation Organization (ICAO), which is helping Ukrainian authorities probe the disaster, said in a statement the plane's digital flight data recorder was still being examined.
ICAO added it was consulting the airline industry and regional aviation bodies about how to assess the risks posed to airspace by armed conflict.
The mother of the three Australian children killed on flight MH17 told a memorial service her "arms would always be reaching for them."
A woman has apparently posted pictures of herself on social media with mascara looted from the Malaysian Airlines flight MH17 crash site.
A large section of plane wreckage and everyday carry-on items like chocolates remain scattered among the wild flowers at the crash site.
