CAIRO: An officer went missing as two Egyptian military amphibious vehicles capsized in the Suez Canal during exercises on Thursday, officials said.
Traffic in the vital waterway was not affected by the accident which occurred away from shipping lanes, canal officials said.
Military and shipping officials said the first armoured vehicle sank due to an "unexpected" technical fault while the second capsized when the crew tried to assist their comrades.
Four conscripts in the first vehicle were brought to shore but an officer was trapped in the second amphibious unit and listed as missing, believed drowned, the sources said.
