The Foreign Office has confirmed the death of a British citizen in Ukraine.
The man's family has been informed, the office said, although it did not announce his identity.
“We are supporting the family of a British national who died in Ukraine and are in contact with the local authorities,” said a Foreign Office representative.
Amid Russia's continuing invasion, the UK government has continued to advise against all travel to Ukraine.
Since the war began in February last year, many people have travelled to Ukraine from the UK, with some taking part in fighting against Russian forces while others engage in volunteer and aid work.
In January, British citizens Andrew Bagshaw and Christopher Parry were killed in eastern Ukraine while trying to conduct a “humanitarian evacuation”.
