Russia unleashed its deadliest attack so far this year on the Ukrainian capital Kyiv and other cities overnight, killing 17 people, including a 12-year-old child, and wounding scores, in drone and missile strikes, officials said on Thursday.

In Russia, a major Ukrainian drone attack on the Black Sea port of Tuapse killed two people, including a 14-year-old girl, injured seven, and sparked a large fire, Russian ‌officials and media reported. The port is home to a major oil refinery as well as an export hub for oil, coal and fertiliser.

Overnight in Kyiv, fires in several different places sent black smoke billowing into the sky. Its heavy smell lingered through the morning as residents and emergency crews cleaned debris scattered around heavily damaged buildings including residential blocks and a hotel.

“I fear for our country and for everything we have. For the people. I feel so sorry for the children. So many people died today,” said Olena Kapustian, 41, standing outside with her son.

Four people, including the child, died in Kyiv, mayor Vitali Klitschko said. Eight people were killed in Odesa and ⁠four in the southeastern city of Dnipro, where Russian attacks set residential buildings ablaze, according to regional officials.

President Volodymyr Zelensky said the night had proven that Russia did not deserve any easing of global policy or lifting of sanctions, with 100 people wounded alongside those killed.
