Mariupol is also facing severe water shortages.

“Water flows for a day or two, then it doesn’t come for three days. We keep buckets and cans of water at home. The colour of the water is so yellow that even after boiling it, it’s scary to drink it,” says James, another Mariupol resident whose name has been changed.

Some have even said the water looks like “coca cola”.

Serhii Orlov, who calls himself Mariupol’s deputy mayor in exile, says the Siverskyi Donets–Donbas Canal which supplied water to the city was damaged during the fighting.

“Only one reservoir was left supplying water to Mariupol. For the current population, that would’ve lasted for about a year and a half. Since occupation has lasted longer than that, it means there is no drinking water at all. The water people are using doesn’t even meet the minimum drinking water standard,” says Serhii.

There are frequent power cuts, food is expensive, and medicines are scarce, residents tell us.

“Basic medicines are not available. Diabetics struggle to get insulin on time, and it is crazy expensive,” says James.

The BBC has reached out to Mariupol’s Russian administration for a response to the allegations about shortages and whether they had found an alternative source for water. We have not got a response so far.

Despite the hardships the most difficult part of living in the city, residents say, is watching what Ukrainian children are being taught at school.

Andrii Kozhushyna studied at a university in Mariupol for a year after it was occupied. Now he’s escaped to Dnipro.

“They are teaching children false information and propaganda. For example, school textbooks state that Donetsk, Luhansk, Kharkiv, Zaporizhzhia, Kherson, Odesa, Crimea and even Dnipropetrovsk regions are all already part of Russia,” says Andrii.
