Russian strikes killed two people and wounded eight in Kramatorsk on Saturday, mayor Oleksandr Goncharenko said, accusing Moscow of having used cluster bombs in the attack on the eastern Ukrainian city. Agence France-Presse reporters heard about 10 explosions go off nearly simultaneously and saw smoke above a park in the city’s south. A woman died at the scene from her wounds, they said. Soon after, another round of explosions was heard in a neighbourhood 2km away.

Russia launched a series of attacks on Friday, according to the Ukrainian armed forces. Seven homes in the village of Veletenske in the Kherson region were destroyed and a nursery was damaged on Friday, but no one was injured, it said. The update, which the Guardian has not verified, also said 10 Iranian-made Shahed drones had been shot down, and that Ukrainian forces had “repelled more than 100 enemy attacks”.

Ukraine said some of the overnight drone attacks hit the relatively peaceful western region of Lviv. Dnipro was also targeted, as was Kyiv, where air defences shot down all attacking drones. Ukraine’s air force said 11 out of 16 drones were destroyed.

The Black Sea grain deal was renewed, according to parties to the agreement. Turkey and the UN announced the initiative was extended, but did not say for how long. A spokesperson for Russia’s defence ministry said it had notified other parties that the deal was extended for 60 days, while a Ukrainian minister said the deal was extended for 120 days.

Another 880 Russian soldiers were reportedly killed on Friday, according to unverified totals published by the Ukrainian army. Its general staff said that it meant more than 164,000 Russian service personnel had been killed since the outbreak of war in February last year. Another five tanks, seven armoured combat vehicles and eight artillery systems were disabled by Ukrainian forces, it said in an update posted on Facebook.

Russia’s Wagner mercenary group plans to recruit about 30,000 new fighters by the middle of May, its founder has said. In an audio message on Telegram on Saturday, Yevgeny Prigozhin said that Wagner recruitment centres, which he said last week had opened in 42 Russian cities, were hiring an average of 500-800 people a day.

Russia would probably introduce wider conscription to boost its military requirements, the UK Ministry of Defence said. In its latest intelligence update, it said Russian Duma deputies introduced a bill to change the conscription age for men from the current 18-27 to 21-30. The law would probably be passed, it said, and come into force in January 2024.

Senior Ukrainian and US security officials met via video link on Saturday, with representatives of Volodymyr Zelenskiy’s government asking for further assistance, including more equipment, weapons and ammunition. Zelenskiy joined the call at the end of the meeting and discussed his forces’ hopes to retake areas Russia has captured.

The US president, Joe Biden, said the international criminal court’s (ICC’s) arrest warrant for Russian leader Vladimir Putin was “justified”. “But the question is – it’s not recognised internationally by us either,” Biden said, referring to the US not being a member of the ICC. “But I think it makes a very strong point.”

The German chancellor, Olaf Scholz, also welcomed the ICC’s decision, saying: “The international criminal court is the right institution to investigate war crimes … The fact is nobody is above the law and that’s what’s becoming clear right now.”

The Russian president, Vladimir Putin, visited the annexed peninsula of Crimea to mark nine years since Russia seized it. Russian state news agency RIA Novosti said Putin visited an art school and a children’s centre. These locations appear to have been chosen in response to the ICC’s arrest warrant, which accuses Putin of being responsible for the abduction of children.

The Biden administration has quietly resumed deportations to Russia, an apparent reversal of the position adopted after Russia invaded Ukraine just over a year ago, when such removals were suspended, the Guardian has learned
