• Russia-Ukraine war at a glance: what we know on day 404 of the invasion

Hello and welcome to our live coverage of the war in Ukraine. I’m Helen Livingstone and I’ll be bringing you the latest developments as they happen.

Our top story this morning:

Prominent pro-war Russian military blogger Vladlen Tatarsky has been killed in a blast at a cafe in central St Petersburg, Russia’s interior ministry has said. Russian media said a bomb was hidden in a statue presented to Tatarsky in a box as a gift. Another 30 people were injured.

Antony Blinken, the US secretary of state, has called for Russia to free the detained American journalist Evan Gershkovich in a rare phone call with his Moscow counterpart. The American’s plea was rejected by Sergei Lavrov, who responded by saying that US officials and media outlets must “not make a fuss” or try to politicise the plight of the Wall Street Journal reporter.

More than three dozen editors of news organisations from across the world have signed a letter condemning Gershkovich’s detention. “Russia is sending the message that journalism within your borders is criminalized and that foreign correspondents seeking to report from Russia do not enjoy the benefits of the rule of law,” says the letter.

Ukrainian president Volodymyr Zelenskiy has said the heavily fought over city of Bakhmut is “especially hot” right now. The comment, in his regular evening address, came as the head of Russia’s Wagner mercenary group, Yevgeny Prigozhin, said that his forces had raised the Russian flag over Bakhmut’s administration building. Prigozhin has issued some premature success claims before and the Guardian could not verify his claim.

Saudi Arabia and other Opec+ oil producers including Russia have announced further cuts in their production amounting to around 1.16 million barrels per day in a surprise move that analysts said would cause an immediate rise in prices.

Russia has suffered up to 200,000 casualties in the war in Ukraine but a “significant number” of these are due to “non-combat causes”, the UK’s Ministry of Defence has said in its latest intelligence update. “Other leading causes of non-combat casualties likely include poor weapon handing drills, road traffic accidents and climatic injuries such as hypothermia,” it said.

Russia plans to form a division of special-purpose submarines that will carry Poseidon nuclear-capable torpedoes as part of the country’s Pacific Fleet by the end of 2024 or first half of 2025, Russia’s Tass news agency has reported.
