Ukraine's defence ministry spokesman Oleksandr Motuzyanyk said on Friday that for, the first time since the start of its invasion, Russia used long-range bombers to attack the besieged port city of Mariupol.

Motuzyanyk said Russia was concentrating its efforts on seizing the cities of Rubizhne, Popasna and Mariupol.

Ukraine's defence ministry spokesman Oleksandr Motuzyanyk said on Friday that street battles were ongoing in the besieged port city of Mariupol, which Russian forces had not managed to completely capture.

Motuzyanyk said active fighting was taking place around Mariupol's Illich Steel and Iron Works, as well as in the port area.
