Western leaders have accused Putin of dragging his feet in U.S.-led peace efforts in an attempt to capture more Ukrainian land.

"There is preliminary information that there were rocket-powered Shahed-type drones," said Interior Minister Ihor Klymenko.

A Russian drone and missile attack on Ukraine’s capital has killed at least six people, including a six-year-old boy, according to Ukrainian President Volodymyr Zelenskyy and other officials.
