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.
