Iran will send to France next month the black boxes from a Ukrainian passenger jet that Tehran's armed forces mistakenly shot down in January, killing all 176 people on board, French aviation investigators said Friday. Iran has requested help with repairing and downloading data from the Cockpit Voice Recorder and the Flight Data Recorder of the Ukraine International Airlines Boeing 737, the Civil Aviation Safety Investigation Authority tweeted. "Technical work (is) planned to start July 20... The safety investigation is led by Iran," it added. sjw/mlr/dl
