Russian president says four Ukrainian regions occupied by Russia will be put under martial law

• What we know on day 238 of the invasion

If you look hard enough, you’ll spot faded yellow signs proclaiming “fallout shelter” around New York City. They are remnants of a cold war programme that signalled spaces within ordinary buildings – from schools to banks to the Brooklyn Bridge – with adequate supplies and walls thick enough for riding out a nuclear blast safely.

Many of these windowless shelters housed little more than rats and sewage before the practice was terminated in 1979. In 2017, the city’s department of education ordered the “misleading” signs removed from its buildings, but many others remain – vestiges of nuclear fears that never materialised.

At least 11 people were killed and 15 wounded at a military training ground in south-west Russia’s Belgorod region when two volunteers opened fire on other troops, the Russian defence ministry said.

Elon Musk has announced his company SpaceX will continue to pay for Starlink satellite internet in Ukraine, a day after suggesting he could not keep funding the project. “The hell with it,” the billionaire tweeted on Saturday. “Even though Starlink is still losing money & other companies are getting billions of taxpayer $, we’ll just keep funding Ukraine govt for free.”

Russia has continued to try to hit Ukrainian’s energy infrastructure but Vladimir Putin’s forces did not appear to have enjoyed any significant success.
