Russia-Ukraine war live: Scholz insists turbine at centre of Russian gas row works; 10m Ukraine border crossings since invasion – as it happened

German chancellor says no reason to hold up return of turbine behind energy standoff; UN says number of border crossings from Ukraine passes 10m mark

Mykola Tochytskyi, deputy minister of foreign affairs, has repeated Ukraine's request for the skies over nuclear installations to be closed to prevent a potential accident and their misuse. He posted to Twitter saying:

The Russian leadership openly threatens the world with its ability to use nuclear weapons, backed by the clear calls to do so by the Russian state media.

For the first time in history, civil nuclear facilities have been turned into military targets and springboards for the Russian army in breach of the non-proliferation provisions on peaceful use of nuclear energy.
