U.S. envoys Steve Witkoff and Jared Kushner have arrived in Moscow to revive efforts to end Russia’s invasion of Ukraine. Ukrainian President Volodymyr Zelenskyy has called for a halt to air attacks during their visit, but Moscow has not publicly responded. The conflict, now in its fifth year, has intensified with both sides escalating aerial attacks. On Friday, a Russian drone hit a key government building in Kyiv. Russian attacks in Ukraine's Dnipropetrovsk region killed five people at an industrial site. Ukrainian air defenses have shot down or suppressed 128 drones.
