The ministry has set up a commission to investigate what caused the accident, according to the statement. It gave no other details, including the identities of the victims.
An investigation found errors in the calculations of the aircraft's weight and center of gravity.
Eight Cuban military personnel died in April 2017 in the crash of a Russian-made aircraft in the mountainous western region of Artemisa.
