Russia-Ukraine war at a glance: what we know on day 412 of the invasion

The Kremlin has said there are no plans for an Orthodox Easter ceasefire in Ukraine, Russian state media reported. The Institute for the Study of War warned that Russia may try to use the upcoming Orthodox Easter holiday on 16 April to delay Ukrainian counteroffensives by calling for a ceasefire out of respect for religion.

The United States on Monday determined that Russia has “wrongfully detained” American Wall Street Journal reporter Evan Gershkovich, effectively saying that espionage charges are bogus and that the case is political.

Russia plans to increase air defences over its north-western border to counter Finland’s accession to Nato, a commander in its aerospace forces has said. Lt Gen Andrei Demin, the deputy commander-in-chief of aerospace forces, also said further reforms of Russian air defences were “undoubtedly planned and will be implemented”.

Col Gen Oleksandr Syrskyi, commander of Ukraine’s ground forces, has accused Russian troops of using “scorched earth” tactics in the embattled eastern city of Bakhmut. The situation in Bakhmut was “difficult but controllable”, he said, adding that the defence of the city continued.

The Russian-installed head of Ukraine’s Donetsk region said Russian forces controlled more than 75% of the besieged city of Bakhmut. It was still too soon to announce a total victory in the battle over Bakhmut, Denis Pushilin said on state television while visiting the embattled city in eastern Ukraine.

Reports claiming that a Russian fighter jet nearly shot down a British surveillance plane off the coast of Crimea in September “contain inaccuracies and do not reflect what happened in international air space over the Black Sea”, a British defence source said on Monday. Britain’s defence secretary, Ben Wallace, disclosed the incident to parliament in October and said at the time that the UK did not consider the case a deliberate escalation, but that it had been due to a technical malfunction.

Ukraine has denied a report that it had been forced to amend some military plans ahead of a long-anticipated counter-offensive because of the leak. Presidential aide Mykhailo Podolyak said Kyiv’s strategic plans remained unchanged but that specific tactics were always subject to change.

More than 200 Russian and Ukrainian soldiers have returned home in a prisoner swap, according to both sides. Russia’s defence ministry said 106 Russian soldiers were released from Ukrainian custody as part of an agreement with Ukraine. Andriy Yermak, chief of staff to the Ukrainian president, said Russia freed 100 Ukrainian prisoners.

The US defence department has said an interagency effort is assessing the impact of the leak could have on US national security and on its allies and partners. Officials say the breadth of topics addressed in the documents – which touch on the war in Ukraine, China, the Middle East and Africa – suggest they may have been leaked by an American rather than an ally.

The documents suggest that without a huge boost in munitions, Ukraine’s air defences could be in peril, allowing the Russian air force to change the course of the war, the New York Times has reported. One of the documents, dated 23 February and marked “Secret”, outlines in detail how Ukraine’s Soviet-era S-300 air defence systems would be depleted by 2 May at the current usage rate.

Only 1,800 civilians are still living in the “ruins” of Avdiivka, the embattled eastern Ukrainian city that had a prewar population of 32,000, according to the local governor. “The Russians have turned Avdiivka into a total ruin,” said Pavlo Kyrylenko, Donetsk’s regional governor. In a separate statement, the Ukrainian general staff said Russian forces were continuing to mount offensive operations around Avdiivka but were suffering heavy losses of personnel and equipment.

Russia continues to prioritise operations around Donetsk in eastern Ukraine “expending significant resources for minimal gains”, the UK Ministry of Defence has said in its daily briefing. The MoD said that over the past seven days Russia had increased armoured assaults around Marinka, a small town about 12 miles (20km) south-west of Donetsk city.

The president of Belarus, Alexander Lukashenko, held a meeting on Monday with Russia’s defence minister, Sergei Shoigu. Lukashenko said he needed guarantees that Russia will defend Belarus “like its own territory” in the case of aggression, state media reported.

Ukraine would like India to be engaged and involved in helping resolve its conflict with Russia “to a great extent”, its first deputy foreign minister Emine Dzhaparova has said. Dzhaparova, the first Ukrainian minister to travel to India since Russia’s full-scale invasion, said the Ukrainian president had requested a phone conversation with India’s prime minister, Narendra Modi.

The Kremlin has said it is hard to imagine France playing a role in brokering peace in Ukraine, since Paris is “both indirectly and directly involved in this conflict on the side of Ukraine”. The French president, Emmanuel Macron, visited China last week, where he urged his Chinese counterpart, Xi Jinping, to bring Russia “back to reason” over the war in Ukraine.

A Russian court has sentenced two men to 19 years in prison each for setting fire to a government building in a demonstration against the war in Ukraine. Roman Nasryev, a former driver for the Russian national guard, and Alexei Nuriev, an officer in the emergency situations ministry, threw a molotov cocktail on 11 October 2002 into an administrative building in the town of Bakal in Russia’s Chelyabinsk region in protest of the war in Ukraine and Russia’s “partial” mobilisation.
