Submarine sent to hunt for black boxes

Ships, planes have found body parts and other debris from the Airbus 320

Egypt has sent a submarine to join the hunt for the flight recorders from the EgyptAir jetliner that crashed in the Mediterranean and killed all 66 people aboard.

Mounting evidence pointed to a sudden and dramatic catastrophe that led to Thursday's crash of EgyptAir Flight MS804 from Paris to Cairo, although Egyptian President Abdel-Fattah el-Sissi said on Sunday that it "will take time" to establish what happened aboard the Airbus A320.
