As UNIAN reported earlier, a recent large-scale prisoner swap between Ukraine and the self-proclaimed republics in Russia-occupied Donbas took place on December 29, 2019, when 76 Ukrainians (12 servicemen and 64 civilians) returned home in exchange for 124 detainees.

Early in January, Ukrainian envoy for the TCG's humanitarian subgroup Valeria Lutkovska said that about 300 people remained in captivity in Donbas.
