The port city is one of the worst places in Ukraine to be, and more than 500 people are stuck in a Russian-seized hospital
More than 500 people who Ukrainian authorities have compared to hostages remain trapped in a Mariupol hospital seized by Russian forces, in a city where 400,000 are either without or with dwindling access to running water, food and medical supplies.
The south-eastern port city has for days been facing a humanitarian catastrophe, besieged by Russian tanks advancing towards its centre amid near constant shelling.
