Ethiopian Airlines said 157 passengers and crew members were killed when one of its jets crashed shortly after take-off from Addis Ababa on Sunday morning.
At least nine Britons and one Irish citizen were among the dead, as were scientists, doctors, aid workers and three members of a Slovakian MP’s family.
The Foreign Office said: “Our staff at the British Embassy in Addis Ababa are continuing to work with the relevant authorities in Ethiopia to obtain further information. We extend our deepest condolences to all those who have lost loved ones and those affected by this tragic event.”
Here is what we know so far about the victims:
Joanna Toole, a 36-year-old from Exmouth, Devon, was heading to Nairobi to attend the UN Environment Assembly when she was killed.
Her father, Adrian, described her as a “very soft and loving” woman whose “work was not a job – it was her vocation”.
“It’s just tragic that she couldn’t carry on to further her career and achieve more,” he told the BBC.
“She was very well known in her own line of business and we’ve had many tributes already paid to her.”
He also said she used to keep homing pigeons and pet rats and travelled to the remote Faroe Islands to prevent whaling.
Joseph Waithaka, who lived in Hull for a decade before moving back to his native Kenya, also died in the crash, his son Ben Kuria said.
Polar expert Sarah Auffret died on the flight as she made her way to Nairobi to talk about a Clean Seas project, her Norway-based employers Association of Arctic Expedition Cruise Operators (AECO) said.
Norwegian media reported that the University of Plymouth graduate was a French-British dual national.
“Sarah was on her way to Nairobi to talk about the Clean Seas project in connection with the UN Environment Assembly this week,” an AECO statement said.
“Words cannot describe the sorrow and despair we feel. We have lost a true friend and beloved colleague.”
