Russia has launched drone attacks on Ukraine overnight Saturday into Sunday killing at least 14 people, including 3 children.

Dozens were injured, according to Ukraine officials.

The attacks marked the most in a single night, according to the BBC.

"Without really strong pressure on the Russian leadership, this cruelty cannot be stopped," Ukraine President Volodymyr Zelensky said. "America's silence will only encourage Putin."

The strikes killed at least three people in the Kyiv region overnight, a Ukrainian official said.
