A member of the UK armed forces has been killed in a crash in Ukraine, the Ministry of Defence (MoD) said.
The MoD said the person died in a road traffic incident on Saturday.
It is understood the incident was not as a result of hostile action.
Their family has been informed and has asked for some time before more details are released.
“Our thoughts and our sympathies are with the individual’s loved ones at this difficult time,” an MoD spokesperson said.
Defence Secretary Wes Streeting said on X: “This is very sad news for the family and for those grieving with them in our Armed Forces.
“My deepest condolences go to them all.”
There is a small number of British personnel in Ukraine who provide security to diplomats and support the country’s armed forces.
British paratrooper George Hooley, 28, was killed in Ukraine in December when he watched Ukrainian forces testing a new defensive capability.
The MoD described his death as a “tragic accident”.
Russia’s full scale invasion of Ukraine is in its fifth year and the conflict continues with fresh strikes on Ukraine including at a gas works and a drone attack on a station on Sunday.
The attack hit a train at Yahodyn station, on the Polish border, shortly after a train carrying Boris Johnson had left ahead of schedule.
Ukraine’s railway operator said the attack may have been aimed at the train carrying the former prime minister, among other dignitaries.
Mr Johnson had been returning from a major conference in Kyiv along with former Swedish prime minister Carl Bildt and a number of European security advisers.
According to a translation from Ukrainian, rail operator Ukrzaliznytsia said in a post on Telegram it was “quite possible” that the drone had been aimed at Mr Johnson’s train.
