Ukrainian officials say at least seven people were killed overnight as Russia launched a wave of deadly drone attacks on the capital Kyiv and parts of eastern Ukraine. Separately, Russia said it shot down scores of Ukrainian drones launched into the Russian-annexed region of Crimea. The fighting came as the White House hinted that Ukraine was prepared to sign a deal granting the U.S. access to Ukrainian resources, including oil, gas and rare earth minerals. Trump said Ukrainian President Volodymyr Zelensky would visit the White House on Friday to sign the agreement. Meanwhile, Russian Foreign Minister Sergey Lavrov says a delegation of U.S. diplomats will meet their Russian counterparts in Istanbul on Thursday to restore diplomatic ties, after the U.S. and Russia withdrew embassy staff at the start of Russia’s full-scale invasion of Ukraine three years ago.
