Russia attacked the Ukrainian capital Kyiv overnight in the biggest drone attack on the city since the start of the war. The attack came as Kyiv was preparing to celebrate the anniversary of its founding on Sunday. Mayor Vitali Klitschko said one person had died.

Ukrainian air forces claimed to have shot down more than 50 drones, but it was not immediately clear if all of them were over Kyiv or around the country.

“Ukrainian history is a long-standing irritant to insecure Russians,” said Andriy Yermak, head of President Volodymyr Zelenskyy’s office.

“Today is another day of sanctions,” Zelenskyy declared on Saturday. He said that 220 companies and 51 individuals are being sanctioned, “most of them are Russians – working for terror.”

“When Russia started this aggression, they looked at the world as if they were looking in a mirror,” he said. “They thought that supposedly everyone in the world was so cynical and looked down on people in the same way that the masters of Russia do. But the world is different: the world helps us protect life.

Meanwhile, Britain’s Defense Ministry said in its daily intelligence update that Russian state-backed media and business groups want the Finance Ministry to authorize a six-day work week “in light of the economic demands of war, apparently without additional pay.

The groups have already petitioned the Russian ministry for a longer working week, the British ministry posted on Twitter.

The update said that Margarita Simonyan, described as a “prominent Russian propagandist,” recently called for citizens to work two more hours in munitions factories each day after their regular jobs.

These calls for a longer workweek without extra pay “echo a Soviet-style sense of social compulsion,” the British update said, adding, “Russian leaders are likely to identify economic performance as a decisive factor for winning the war.”
