Iran will not give the black box of the crashed Ukrainian airliner to planemaker Boeing, the head of Tehran's civil aviation organisation was quoted as saying on Wednesday.
Ali Abedzadeh also said it was not clear which country Iran would send the box to so that its data could be analysed, semi-official Mehr news agency reported.
A Ukraine International Airlines Boeing 737 crashed earlier on Wednesday, killing all 176 people aboard shortly after taking off from Tehran's Imam Khomeini airport.
An Iranian official was quoted as saying both boxes were damaged but that it was believed their data could still be retrieved.
