The time in Kyiv is just coming up to 9pm. Here is a round-up of the day’s main news stories:

• Footage from social media appears to show a Ukrainian missile strike on a large ammunition store in the town of Nova Kakhovka, in Russia-occupied Kherson.
• Ahead of scheduled four-way talks in Turkey to unblock Ukraine’s grain exports, Ukraine’s foreign ministry said the grain issue must be resolved under the auspices of the United Nations.
• Russian president Vladimir Putin will visit Iran next week, the Kremlin said, a day after the US warned that Tehran could provide Moscow with drones for its action in Ukraine.
• The death toll from a Russian missile attack on a five-storey apartment building in the town of Chasiv Yar in eastern Ukraine has risen to at least 34.
• The UN human rights office (OHCHR) said on Tuesday that more than 5,000 civilians had been killed in Ukraine since Russia invaded on 24 February, adding that the real toll was probably much higher.
• The European Union has so far frozen €13.8bn (£11.7bn) worth of assets held by Russian oligarchs, other individuals and entities sanctioned for Moscow’s war against Ukraine, the bloc’s top justice official said on Tuesday.
• Russia has claimed to have killed a significant number of foreign mercenaries fighting in Ukraine in the last three weeks, including 23 from Great Britain.
• An official at the self-proclaimed Donetsk People’s Republic says that the appeals over the death sentences of Aiden Aslin, Shaun Pinner and Saaudun Brahim will be dealt with within a month. UK foreign secretary Liz Truss has said she “utterly condemns” the sentencing, stating: “They are prisoners of war. This is a sham judgement with absolutely no legitimacy.”
• Brazil is looking to buy as much diesel as it can from Russia and the deals are being closed “as recently as yesterday,” Brazilian foreign minister Carlos Franca said on Tuesday, without giving further details on the transactions.

That’s it from me, Tom Ambrose, for today. My colleague Richard Luscombe will be along shortly to continue bringing you all the latest news from Russia’s war on Ukraine.

The Russian-installed administration claims at least seven people were killed in the blast. The statement could not be immediately verified, though the footage shows a large explosion lighting up the night sky, exploding ammunition and plumes of smoke.
