Forensic doctors in Bucha, north of Kyiv, have confirmed that dozens of civilians who died amid Russia's occupation of Ukraine were killed by tiny metal darts fired from Russian shells.

The pathologists, who are conducting postmortem analyses of bodies which were exhumed from mass graves following the withdrawal of Russian troops from the region early this month, found the darts - known as 'flechettes' - in the corpses' head and chest cavities.
