Ukraine's Air-Raid Shelters Found Unusable and Locked, Prompting Investigation.

Nearly a quarter of Ukraine's air-raid shelters are locked or unusable, according to an inspection by the interior ministry, raising concerns about civilian safety. The announcement comes after a woman in Kyiv died waiting outside a locked shelter during a Russian missile attack. Four people have been detained in a criminal probe into the woman's death, with one security guard remaining under arrest. Kyiv mayor Vitali Klitschko has received over a thousand complaints regarding locked, dilapidated, or insufficient air-raid shelters. Russian shelling has killed at least four civilians across Ukraine in the previous 24 hours.
