Search operations under way as drones hit residential buildings; US considers lifting more sanctions on Russian oil. What we know on day 1,473

Ukraine issued a nationwide air alert early Saturday, as Russian strikes wounded 10 people in the Kharkiv region, authorities said. The Kharkiv regional military chief, Oleg Synegubov, said at least three people were treated in hospital, including an 11-year-old boy, after a strike on a residential building. “According to preliminary information, five people are trapped under the rubble of the house,” he posted on Telegram. The Kharkiv mayor, Igor Terekhov, said a search operation was under way to rescue them. In the city of Chuhuiv in the Kharkiv region, two people were wounded in an “enemy drone attack” on a house, the local mayor said.

The Trump administration is considering lifting sanctions on more Russian oil, the US treasury secretary, Scott Bessent, has said. On Thursday Washington temporarily eased sanctions to allow India to buy from Moscow amid a surge in global oil prices as the US-Israel war on Iran all but halted shipping activity in the strait of Hormuz. Bessent insisted the new measures were not aimed at easing sanctions imposed on Russia over its conduct in negotiations to end the war in Ukraine, but instead only affect supplies already in transit.
