Ukraine's SBU security service said on Saturday at least 20 civilians were killed in the Russian shelling of a civilian convoy in late September in an eastern "grey zone" between Russian-controlled and Ukrainian-controlled territory.
Seven vehicles were hit in shelling between occupied Svatove in Luhansk region and Ukrainian-held Kupiansk which Kyiv recaptured in the Kharkiv region last month, the SBU said in a statement.
The SBU published graphic images of destroyed civilian vehicles on a track next to a railway line and what appeared to be the charred remains of people. Two bodies were seated in the driving seats of their cars; one was holding the steering wheel.
