Russia has launched a massive aerial attack on Ukraine, targeting civilian areas with hundreds of drones and dozens of missiles. Officials say the assault killed at least 16 people and injured over 100. The attack, which stretched from daytime into the night, is the largest in almost two weeks. The Russian Defense Ministry claims it was in retaliation for Ukrainian strikes inside Russia. Ukrainian President Volodymyr Zelenskyy has been seeking more air defense systems from allies. Ukraine's air force reports that air defenses shot down or disabled most of the incoming targets.
