At least five people were killed and 10 were injured in the latest heavy Russian airstrikes on Ukraine, President Volodymyr Zelensky said on Sunday. Zelensky reported on social media that Russia used more than 50 missiles and cruise missiles, as well as around 500 drones, in a combined attack on the country. Authorities stated that four people died in the Lviv region in western Ukraine near the Polish border. Zelensky further reported that the regions of Zaporizhzhya, Sumy, Kharkiv, Odessa and Kherson were also affected and that Russia again targeted vital infrastructure in these regions. Rescue and reconstruction efforts are under way in many places, he said. “We need more protection and a faster implementation of all defence agreements, especially in the area of air defence, to render this air terror meaningless,” said Zelensky. A ceasefire in the sky is possible, the president stated, without providing details, adding this could pave the way for genuine diplomacy. The US and Europe must now act to force Russian President Vladimir Putin to relent, Zelensky said.
