“If Peresvet blinds, then the new generation of laser weapons lead to the physical destruction of the target – thermal destruction, they burn up,” Mr Borisov said.
However, an official with the US Department of Defense said he had not seen “anything to corroborate reports of lasers being used” in Ukraine.
Meanwhile, Ukrainian President Volodymyr Zelensky mocked the Russian claim, comparing it to the so-called “wonder weapons” that Nazi Germany claimed to be developing during World War Two.
“The clearer it became that they had no chance in the war, the more propaganda there was about an amazing weapon that would be so powerful as to ensure a turning point,” he said in a video address.
“And so we see that in the third month of a full-scale war, Russia is trying to find its ‘wonder weapon’… this all clearly shows the complete failure of the mission.”
