VIDEO | Fire ignites on crane vessel at Russian shipyard

The yard sits more than 800 kilometres away from the border with Ukraine. However, despite speculation that the incident may have been the result of sabotage or an external attack, the facility had never been included among key installations in Nizhny Novgorod that were targeted by Ukrainian strikes.

Russian officials have not issued statements on who the perpetrators might be, while Ukraine has not claimed responsibility for the incident.

News outlet The Kyiv Independent said it could not yet verify Russian state media claims that one person was killed in the fire.
