Cargo documents and manifests seen by CNN, as well as eyewitness accounts and photographic evidence, confirm that arms were transported between Addis Ababa’s international airport and airports in the Eritrean cities of Asmara and Massawa on board multiple Ethiopian Airlines planes in November 2020 during the first few weeks of the Tigray conflict.
It’s the first time this weapons trade between the former foes has been documented during the war. Experts said the flights would constitute a violation of international aviation law, which forbids the smuggling of arms for military use on civil aircraft.
Atrocities committed during the conflict also appear to violate the terms of a trade program that provides lucrative access to the United States market and which Ethiopian Airlines has benefited greatly from.
Ethiopian Airlines is a state-owned economic powerhouse that generates billions of dollars a year carrying passengers to hubs across the African continent and all over the world, and it is also a member of the Star Alliance, a group of some of the world’s top aviation companies.
The airline previously issued two denials about transporting weapons.
Responding to CNN’s latest investigation, Ethiopian Airlines said it “strictly complies with all National, regional and International aviation related regulations” and that “to the best of its knowledge and its records, it has not transported any war armament in any of its routes by any of its Aircraft.”
The governments of Ethiopia and Eritrea did not respond to CNN’s requests for comment.
Long-simmering tensions between Ethiopia’s government and the ruling party in the Tigray region exploded on November 4, when Ethiopia accused the Tigray People’s Liberation Front of attacking a federal army base.
Documents obtained by CNN indicate that flights carrying weapons between Ethiopia and Eritrea began at least as early as a few days after the outset of the Tigray conflict.
On at least six occasions — from November 9 to November 28 — Ethiopian Airlines billed Ethiopia’s ministry of defense tens of thousands of dollars for military items including guns and ammunition to be shipped to Eritrea, records seen by CNN show.
The documents, known as air waybills, detail the contents of each shipment. In one document, the “nature and quantity of goods” is listed as “Military refill” and “Dry food stuff.” Other entries included the description “Consolidated.” The records also had abbreviations and spelling mistakes such as “AM” for ammunition and “RIFFLES” for rifles, according to airline employees. They told CNN the spelling errors were introduced when the contents were manually entered by employees into the cargo database.
Benno Baksteen, chairman of DEGAS, the Dutch Expert Group Aviation Safety, told CNN that these waybills were required for all commercial flights as the crew on board need to know the contents of the cargo to ensure they are transported safely.
On November 9, five days after Abiy ordered a military offensive in Tigray, records show an Ethiopian Airlines flight transported guns and ammunitions from Addis Ababa to Asmara, Eritrea’s capital.
An air waybill and a cargo manifest from that date show that Ethiopian Airlines charged Ethiopia $166,398.32 for about 2,643 pieces of “DFS & RIFFLE WITH AM (sic)” on that flight. DFS is a reference to “dry food stuff,” according to airline sources.
Another air waybill from a few days later, November 13, has the same shipper and consignee. The content of that shipment was “military refill and dry food stuff,” according to the document. The shipments came at a time of increased military activity; security sources in the region told CNN the Eritreans needed re-supply for the fight in Tigray.
Cargo documents show that the series of flights between Ethiopia and Eritrea continued until at least November 28, 2020.
Some current and former Ethiopian Airlines employees, who spoke on condition of anonymity for fear of repercussions, said the flights continued past this date but that the majority of arms trips to Eritrea were in November.
Both cargo and passenger planes were used in the operation, though CNN has no evidence that commercial passengers were on any of the flights carrying weapons. Many of these flights do not appear on popular online flight tracking platforms such as Flightradar24. When they do, the destination in Eritrea is often not visible and the flight path vanishes once the plane crosses the border from Ethiopia.
The employees told CNN the staff could manually turn off the ADS-B signal on board to prevent the flights being publicly tracked.
The flights were often assigned the same flight numbers, primarily ET3312, ET3313 and ET3314, with ‘ET’ being the code for Ethiopian Airlines. All the planes mentioned in the cargo files seen by CNN are American-made Boeing aircraft. The airline has been in a long relationship with the US aviation giant.
A Boeing representative declined to comment.
Ethiopian Airlines workers described witnessing other airline employees loading and unloading arms and military vehicles on flights directed to Asmara. A few even claimed they helped load the weapons on the planes themselves. All spoke of being ethnically profiled for being Tigrayan.
CNN has seen the Ethiopian Airlines’ ID cards of these employees and confirmed their identities.
One former employee told CNN they were instructed at Addis Ababa’s Bole International Airport to load guns and four military vehicles onto an Ethiopian Airlines cargo plane that was due to fly to Belgium but was sent instead to Eritrea.
“The cars were Toyota pickups which have a stand for snipers,” the employee said. “I got a call from the managing director late at night informing me to handle the cargo. Soldiers came at 5 a.m. to start loading two big trucks loaded with weapons and the pickups.”
“I had to stop a flight to Brussels, a 777 cargo plane, which was loaded with flowers, then we unloaded half of the perishable goods to make space for the armaments.”
The former employee warned soldiers that the vehicles were carrying far more gas than was allowed under international air transport rules, but said they were overruled after a direct call from an army commander.
“He [the commander] said we are going to war and we need the fuel to be loaded,” the employee said. “Then I referred the issue to my manager and my manager took responsibility and allowed them to load it.”
The flight, loaded with both weapons and flowers, traveled to Eritrea, then returned to Addis before flying on to Brussels the following day, the employee said. CNN cross-referenced this testimony with Flightradar24 and found the record of an Ethiopian Airlines aircraft returning from the direction of Eritrea and flying to Brussels the next day, but could not independently verify it was the same flight referred to by the employee.
Days later, the employee said they were temporarily suspended from work. They believe they were suspended for being Tigrayan but also for the incident with the soldiers. The employee fled Ethiopia in March.
Ethiopian Airlines told CNN in its statement that no employees had been suspended or terminated due to their ethnic background.
It appears to be not the only long-distance international flight with unplanned stops. A flight from Addis Ababa to Shanghai on November 9, 2020, took a long detour via Eritrea according to the ADS-B signal that tracks the route on Flightradar24.
Several employees at the Addis Ababa airport said they saw multiple weapons flights leave for Eritrea each day at the outset of the conflict. They also spoke about flights carrying weapons from Eritrea back to Ethiopia. It’s unclear why armaments were being transferred back to Ethiopia.
One said they saw tanks and heavy artillery loaded onto planes coming to Addis Ababa, while small arms — mortars, launchers — were dispatched to Asmara. Employees told CNN they believed the smaller weaponry were being sent to Asmara to arm Eritrean troops.
All the employees said they were instructed by the airline to delete photos of the weapons from their phones. Not all of them did.
In June, photos circulated on social media platforms showing crates containing mortars on board an Ethiopian Airlines flight and the same crates being loaded on the plane in Massawa, Eritrea.
The company released a statement strongly denying the allegation that its planes were transporting weapons and claimed the photos were photoshopped.
However, CNN has corroborated the photos using visual analysis techniques, interviews and documentary evidence, dating them to a 777 Freighter cargo flight that flew from Ethiopia to Eritrea and back between November 8 and 9.
The images show a variety of mortars stacked up in the crates. Dan Kaszeta, a London based defense specialist and an associate fellow at the Royal United Services Institute, identified the mortars as 832-DU 82mm mortar rounds, originally made in Russia but with many versions subsequently manufactured, including in Bulgaria.
CNN has contacted the Bulgarian government and reached out to Bulgarian arms producers but received no response. According to the EU’s public database, Bulgaria sold weapons to Ethiopia as recently as 2020.
Another image features an employee wearing a uniform that matches with the Ethiopian Airlines uniform. The interior of the plane also fits the layout of an Ethiopian Airlines 777F cargo plane. The expiry date of the Emirates SkyCargo straps tightened around the crates — November 2023 — can be seen in the photos. Since these particular types of cargo straps — TSO C172 — have a lifespan of three years, they would have been used in November 2020 at the earliest. CNN has confirmed that these Emirates SkyCargo straps have been used on other Ethiopian Airlines flights.
A representative for TSO C172 cargo straps manufacturer AmSafe Bridport declined to comment. CNN has sought comment from Emirates SkyCargo.
CNN has learned that the cargo plane in question took off on November 8 from Addis Ababa empty before landing in Massawa, where local workers were tasked with manually loading it with a variety of weapons, including these mortars.
A cargo manifest from that day, seen by CNN, confirms the flight was empty when it reached Massawa.
A screenshot from the Ethiopian Airlines internal database taken by an employee and sent to CNN reveals a flight on November 8 to Massawa that is hidden from flight tracking sites. The weapons were then dropped in Bahri Dar, Ethiopia, before the aircraft returned to Addis Ababa on November 9.
‘A lot of legal repercussions’
Several aviation experts CNN spoke to on these findings said Ethiopian Airlines appeared to be in violation of the Convention on International Civil Aviation, commonly known as the Chicago Convention, which prohibits commercial carriers from transporting “munitions of war or implements of war.”
Pablo Mendes de Leon, professor of air and space law at The Hague, told CNN there are several indications that these flights were commercial flights — not military or state aircraft — including “that [the flights] carry a commercial flight number of Ethiopian Airlines in conjunction with the fact that an airway bill has been issued.”
“I have now arrived at the conclusion that [these flights have] been operated by civil aircraft falling under the terms of the Chicago Convention,” Mendes de Leon said, adding that CNN’s findings “have a lot of legal repercussions and conditions, all of which may not have been met.”
Ethiopia’s status as a regional economic powerhouse is partly dependent on Ethiopian Airlines’ dominance in cargo. The country and the airline have benefited from an American trade program that provides favorable access to the US market for countries that meet certain criteria.
This relationship matters for both countries: in 2017, US exports to Ethiopia consisted primarily of aircraft and aircraft components from Boeing, valued at more than $857 million.
But a clause in the US African Growth and Opportunity Act (AGOA) stipulates that eligible nations must not engage in “gross violations of internationally recognized human rights.”
Previous CNN investigations found atrocities committed by the Ethiopian government and its allies bore the hallmarks of genocide and ethnic cleansing.
On Tuesday, a spokesperson told CNN that Tai’s office would conduct its next review of eligibility for AGOA in 2022, “based upon compliance with standards that include adherence to internationally recognized workers’ rights, rule of law, and human rights.” After the review, Tai could “possibly recommend that the President add or remove certain countries from AGOA beneficiary country status.”
