Three children among eight dead in Russian strikes on Ukraine, officials say

In neighbouring Poland, Prime Minister Donald Tusk was heading to the site of a 10m-crater (33ft), after "a violation of Polish airspace occurred" during Russia's attack on Lviv.Polish armed forces said they had mobilised on-duty fighter jets during the strikes, after detecting at least a dozen missiles over western Ukraine that could have posed a threat to Polish airspace. The closest one was observed about 5km from the Polish border at 03:29, after which it changed direction and headed eastwards.The military said they had subsequently located the crater with scattered debris on Polish soil - in a field about 2km away from the village of Tarnawa-Kolonia, Lublin province, in the south. The site has been secured, they said. Police said they had received a report of a powerful explosion in the area. Poland's prime minister said the crater was likely caused by a Russian missile, but investigations were still ongoing."All the indications are that it was a Russian Kh-101 ballistic missile, but we want to be 100% certain about the type of missile and who launched it," Donald Tusk said at a specially convened meeting in Lublin.Meanwhile in Russia, a regional official reported an overnight attack on the warehouse of a retailer in the city of Penza.
