Iranian Civil Aviation Organization said it had asked its French and US counterparts, the BEA and NTSB respectively, to provide a list of the equipment required to read the black boxes from the Boeing airplane downed near Tehran on January 8.
Report says, citing Al Arabiya, that Iran sought the transfer of the required equipment, but neither the BEA nor NTSB had "so far responded positively" to such a transfer.
According to the TV channel, Iran has no such equipment to decode the data.

Among the victims were the citizens of Ukraine, Canada, Great Britain, and Germany. The Islamic Revolutionary Guard Corps assumed responsibility for the tragedy.
