Ukrainian President Volodymyr Zelensky said Saturday that counteroffensive and defensive actions were underway against Russian forces, asserting that his top commanders were in a “positive” mindset as their troops engaged in intense fighting along the front line.

The Ukrainian leader, at a Kyiv news conference alongside Canadian Prime Minister Justin Trudeau, responded to a question about Russian President Vladimir Putin’s comment a day earlier that Ukraine’s counter-offensive had started — and Ukrainian forces were taking “significant losses”.

Zelennsky said that “the counteroffensive, defensive actions are taking place in Ukraine. I will not speak about which stage or phase they are in”.

“I am in touch with our commanders of different directions every day,” he added, citing the names of five of Ukraine’s top military leaders. “Everyone is positive. Pass this on to Putin.”

Trudeau, the first foreign leader to visit Ukraine since devastating floods caused by a breach in a Dnieper river dam, offered up monetary, military and moral support for Ukraine. He pledged $500 million in new military aid, on top of $8 billion that Canada has already provided since the war began in February 2022, and announced $10 million for humanitarian assistance for the flood response. Trudeau said the dam’s collapse was “a direct consequence of Russia’s war,” but he didn’t blame Moscow directly.
