Air raid sirens sent people running for shelter in Ukraine's besieged south-eastern city of Mariupol on Sunday as the Russian defence ministry said its forces had advanced 11km (7 miles) and reached five towns north of the city – a claim that Ukraine denied. Drone footage posted by Ukraine's Azov battalion on social media showed a powerful explosion destroying a high-rise building on Monday. The drone footage shared by the special forces unit, which includes members of a far-right political group, also showed fires blazing and thick, dark plumes of smoke rising from several buildings in the city.
