Kyiv —

Russia has launched missiles toward Kyiv and other Ukrainian cities, the Ukrainian Air Force said early Thursday local time, in a move that comes just hours after President Volodymyr Zelensky warned Moscow was preparing a “massive attack.”

In addition to ballistic missile strikes on the Ukrainian capital, Dnipro and Kryvyi Rih were also under attack, the air force said.

After an initial wave of attacks, the air force said “more ballistic missiles” were flying toward Kyiv.

“The threat of further attacks remains,” Kyiv’s Mayor Vitali Klitschko said, urging people to stay in shelters.
