KYIV, Ukraine (AP) — In a military cemetery in Kyiv, a brother and sister walk between the crosses, carrying a bunch of carnations. Each cross in that section bears the same words: “unknown defender of Ukraine,” with an ID number below and a note that identification is ongoing.

One grave stands out: beneath the inscription, a photo was later attached, showing Ihor Yalynych, a soldier last seen alive in Kharkiv region in 2022. After four years of searching, Stanislav and Oleksandra Yalynych found their father.
