Briton Paul Urey, who was captured by Russian-backed separatists in Ukraine, has died in detention, Report informs, citing BBC.
The 45-year-old Urey was detained in the self-proclaimed Donetsk People's Republic (DPR) in April and accused of being a mercenary.
He was taken prisoner along with another man, Dylan Healy, while reportedly trying to conduct a humanitarian rescue mission on April 25.
The pair were detained at a checkpoint south of the south-eastern city of Zaporizhzhia, reportedly to rescue a woman and her family trapped by the fighting.
Mr. Urey's mother had said she was extremely worried for his welfare because he had type 1 diabetes and needed insulin.
Officials from the DPR, who were holding Mr. Urey, said he died in captivity on July 10 from underlying health conditions and "stress".
