European foreign ministers have called out Moscow for delaying a ceasefire in Ukraine as the Kremlin spokesperson Dmitry Peskov said it would be “a drawn-out process”. The European Union’s foreign policy chief, Kaja Kallas, said on Monday: “Russia is playing games and not really wanting peace. So our question is, how can we put more pressure on Russia.” There should be some kind of deadline for Russia accepting a ceasefire in Ukraine, the Polish foreign minister, Radoslaw Sikorski, said on Monday in Madrid where like Kallas he was attending an EU foreign ministers’ meeting.

The French foreign minister, Jean-Noel Barrot, said in Madrid that Russia owed a clear response to the US on whether it wants to go on a peace path at all. Donald Trump, the US president, has threatened sanctions against the remaining buyers of Russian oil if Vladimir Putin does not agree to a ceasefire soon. Russia has effectively rejected a US proposal for a 30-day general ceasefire; Moscow instead wants a partial ceasefire on the Black Sea but has sought to impose far-reaching conditions.

British, French and Ukrainian military leaders will meet again in the coming days to build on “real momentum” in efforts to boost Ukraine’s security, said the office of Keir Starmer, the British prime minister. The meeting to “drive forward the next stage of detailed planning” was agreed on a call between Starmer and Zelenskyy. Britain and France are spearheading a “coalition of the willing” plan that includes putting troops in Ukraine as what have been variously described as a peacekeepers, ceasefire monitors or a reassurance force.

Russian forces shelled a frontline settlement in Ukraine’s south-east Zaporizhzhia region on Monday, killing a 66-year-old woman and injuring five, said the regional governor, Ivan Fedorov. Zaporizhzhia is one of four regions partly occupied by Russian forces. Kharkiv, Ukraine’s second-largest city, came under another Russian drone attack overnight, injuring three people, the Ukrainian interior ministry said on Monday. Russia said its air defences shot down 66 Ukrainian drones early on Monday over three Russian regions.

Volodymyr Zelenskyy called on Monday for Russia to be punished for more than 183,000 alleged war crimes. Zelenskyy, with first lady Olena Zelenska and visiting European officials, paid tribute in Bucha to victims of Russia’s month-long occupation of the town which lies north-west of the Ukrainian capital, Kyiv. It was invaded in February 2022 by Russian troops who were expelled by Ukrainian defenders the next month.

Russian troops are accused of atrocities including executions, rapes and torture during the Bucha occupation. The Russian forces committed more than 9,000 crimes in the area around Bucha including 1,800 killings, according to Ukraine’s acting prosecutor general, Oleksiy Khomenko. Khomenko said on Monday that Ukrainian authorities had so far charged 178 individuals and convicted 21. He said Kyiv was continuing to work with the ICC and 25 other countries that were carrying out their own investigations. “Ukraine will not stop on the path of bringing those responsible to justice.”

Ukraine said it was working on changes to a draft agreement with the US over sweeping access to Ukrainian natural resources, referred to as critical minerals or by Donald Trump as “rare earths”. Trump has warned Kyiv of “big problems” if it rejects the US proposal. “We will try to pass on Ukrainian proposals sometime by the end of this week,” said a Ukrainian official, speaking on condition of anonymity. They said talks had been held online with the US side on Friday and that the Ukrainian team would report to Zelenskyy “today or tomorrow … then we will prepare our position and send it to [the US]”.

The Kyiv source also told the Agence France-Presse news agency that Europe was taking an interest in the agreement, following reports that some of its provisions could contravene Kyiv’s commitments to the EU, which it is seeking to join. “The agreement must take into account our obligations in the context of association with the EU and Ukraine’s movement towards the EU,” the source said.

Sweden will donate 16 billion kronor (€1.4bn) in fresh military aid to Ukraine, the government said on Monday – the largest such package from the Nordic country since Russia’s 2022 invasion. Most of it would go towards the acquisition of newly produced materials, “mainly from the Swedish, but also the European defence industrial base”, said the Swedish government. It is the 19th batch of military aid that Sweden has provided to Ukraine, with the total estimated at 80 billion kronor, according to the government.

When it announced a previous aid package in January, Sweden said it was moving from donating weapons from stockpiles to purchasing new arms. Earlier in March it said it would donate 18 of its home-developed Archer mobile artillery systems to Ukraine, of which it had previously donated eight. It has sent 50 of its CV90 armoured combat vehicles and “around 10” Leopard 2 tanks, as well as anti-air missile systems.

Vladimir Putin has ordered 160,000 servicemen be drafted by 15 July, a higher figure than previous conscription drives. Russian men are liable to be drafted for mandatory military service through bi-annual call-ups. The Kremlin and defence ministry say they are not sent into combat; however, Kyiv has said throughout the conflict that it has taken Russian conscripts captive.
