At least five people, including an infant, his mother, and grandmother, were killed on Thursday night after a Russian drone attack on the northern Ukrainian city of Pryluky, officials said.

Six drones hit a residential area in the city shortly before dawn, injuring nine others, according to authorities. The child killed was the grandson of the local fire chief, Ukraine's Interior Minister Ihor Klymenko said.

The fire chief, identified by local officials as 50-year-old Oleksandr Lebid, "arrived to respond to the aftermath right at his own home,” Ukrainian President Volodymyr Zelenskyy said in a post on Telegram. “It turned out that a Shahed drone hit his house,” said the President.
