Suspilne, Ukraine’s state broadcaster, reports on its official Telegram channel that this morning the border village of Chernatske in Sumy oblast has been struck. It writes: “Twenty hits were recorded, probably from barrel artillery. The infrastructure of the village was damaged – a cultural centre and a children’s playground, as well as five private houses.”

The UK Ministry of Defence says Russia’s 10th tank regiment has borne the brunt of the assault of Avdiivka and has likely lost a “large portion of its tanks” while attempting to surround the town from the south.

Berlin says Moscow’s announcement is ‘another attempt at nuclear intimidation’

• What we know on day 397 of the invasion

Russia plans to complete coastal infrastructure needed to host nuclear submarines in the Pacific Ocean, Tass news agency reported on Monday.

The nuclear submarines will be capable of carrying the Poseidon nuclear-capable super torpedos first produced in January, four years after they were announced.

A policy of dramatic fiscal austerity that comes at the expense of the fabric of Ukrainian society and the state will have huge long-run costs. The EU, the United States and other outside supporters can soften this dilemma best a. by providing more generous funding and b. by urging Kyiv towards a strategy of civilian as well as military state-building, not by replacing domestic national institutions with international agencies, but by promoting the mobilization of local institutions and agencies.
