"If the Russians are using this level of specialists in urban combat, they are probably facing some difficulties," Ivan Petrychak, spokesperson for the 24th Separate Mechanized Brigade, said.

Previously, Polish Prime Minister Donald Tusk accused the Russian intelligence services of orchestrating a May 2024 arson attack on the Marywilska shopping centre in Warsaw.

"Perhaps in some areas, the intensity decreased slightly to create an image of compliance with their own announcement. But in reality, (Russia) continued attacks every day, using all available weapons — including aircraft to drop guided bombs on Ukraine," Andrii Demchenko, spokesperson for Ukraine’s State Border Guard Service, said.

Beijing supports all efforts toward achieving peace in Ukraine, Chinese Foreign Ministry spokesperson Lin Jian said on May 12 when asked about Kyiv and Europe's proposal for a 30-day truce.

"There is no point in prolonging the killings. And I will wait for Putin on Thursday in Turkey," President Volodymyr Zelensky said.

"I invited His Holiness to make an apostolic visit to Ukraine. Such a visit would bring real hope to all believers and to all our people," Zelensky said.

Presidential Office chief Andriy Yermak voiced doubt about leading negotiations with anyone from Russia except President Vladimir Putin, implying only the Russian leader can make real decisions.

This includes at least seven people injured in drone attacks overnight on May 12, a date from which Kyiv and its allies put forward a demand for a 30-day unconditional truce, a step that Moscow continues to reject.

"When European unity becomes inconvenient, disinformation goes so far as to make a simple tissue look like drugs," the Elysee Palace reacted to a fake story pushed by Russia.

The comments came after Trump urged Ukraine to agree to direct negotiations with Russia, which has invited Kyiv to peace talks in Istanbul on May 15, without first agreeing to halt military operations.

A Russian drone hit a civilian freight train in Donetsk Oblast on May 12 and injured its driver, Ukrainian Railways said amid Kyiv's calls for a ceasefire.

The number includes 1,170 casualties that Russian forces suffered over the past day.
