Today, a commercial air cargo flight on a planned non-stop flight from Stockholm, Sweden, to Johannesburg, South Africa went down in the Sahara Desert in North Africa after a technical fault interrupted fuel flow to its engines. The crew made a successful emergency landing at an abandoned WWII airbase, but the aircraft soon came under attack by a band of rebel tribesmen who are at war with their government, setting it afire and destroying the cargo. All nations having any connection to the cargo and the flight have ratified the Montreal Convention. Analyze the extent of the airline's liability, if any, to the shippers for destruction of their cargo, explaining your decision process clearly.
