At least 47 people, including five children, were injured on Sunday after Russian missiles struck a shopping mall and events complex in Ukraine's northeastern city of Kharkiv, officials said.

Earlier in the day, Russia said Kyiv had launched one of the biggest drone attacks against it since the full-scale war began, targeting power plants and an oil refinery, while Moscow's forces made further gains toward a key town in eastern Ukraine.

The Kharkiv attack prompted Ukrainian President Volodymyr Zelenskyy to renew calls on allies to allow Kyiv to fire Western-supplied missiles deeper into enemy territory and reduce the military threat Russia poses.
