Germany’s defence minister has accused Russia of conducting an “information war” aimed at creating divisions within the country, in his first comments after the publication of an audio recording of a meeting of senior German military officials. Russian media on Friday published a 38-minute recording of a call in which German officers were heard discussing weapons for Ukraine and a potential strike by Kyiv on a bridge in Crimea, prompting officials in Moscow to demand an explanation.

President Volodymyr Zelenskiy on Sunday called for Ukraine’s western partners to summon the political will to provide Kyiv with necessary military supplies or the world will face “one of the most shameful pages of history.” Zelenskiy issued his appeal as a US package to provide military and other assistance remains blocked by disagreements in Congress. A clearly angry Zelenskiy, speaking in his nightly video address, said the world had to “react firmly” to ensure that the war becomes a “hopeless” enterprise for Kremlin leader Vladimir Putin, who wants only “war and death.”

The death toll from a Russian drone strike on an apartment building in Odesa on Saturday rose to 12, after rescue workers found another four bodies. Among the dead was an eight-year-old girl, discovered near the body of her older brother, who had been uncovered earlier, regional governor Oleh Kiper said. The dead also included a mother who was found holding her baby, as well as a toddler and a second baby.

Five people were injured overnight by Russian shelling on residential areas in Myrnohrad and Pokrovsk in Donetsk oblast, according to the regional prosecutor’s office. Ukraine’s interior ministry also reported one death and three people wounded in the southern Kherson region on Sunday after Russian strikes.

People were still queueing up to place flowers on Alexei Navalny’s grave in Moscow’s Borisovskoye cemetery on Sunday. The pile of floral tributes is growing despite state intimidation as Russians pay tribute to the late opposition leader.

Turkey believes it is time for ceasefire talks to start in Ukraine, its foreign minister, Hakan Fidan, said at a press conference on Sunday. Fidan said: “A dialogue for a ceasefire [in Ukraine] should start. That doesn’t mean recognising the occupation [by Russia], but issues of sovereignty and ceasefire should be discussed separately.”

The wife of Vladimir Kara-Murza, one of Russia’s most high profile political prisoners, says it has taken two years to secure a meeting with the UK government, despite him being a British citizen. Kara-Murza is serving a 25-year sentence in a Siberian jail and his wife, Evgenia, told the Observer she only met David Cameron on Friday.

Ukraine’s border with Poland remains blocked at all six checkpoints to trucks because of protests by Polish farmers about the import of grain from Ukraine, according to local reports. State Border Guard spokesperson Andrii Demchenko said on national television that about 2,400 trucks had been waiting to pass the border as of Sunday, according to a report in The Kyiv Independent.

Ukraine launched a mass drone attack on the Russian-occupied Crimean peninsula early on Sunday, with unconfirmed reports of powerful explosions near the port of Feodosia. Russia’s defence ministry said Ukraine launched 38 drones and that its air defences destroyed all of them. It did not say whether any damage or casualties resulted from the attack in a statement on its Telegram channel.
