Ukraine's health minister has accused Russian authorities of committing a crime against humanity by blocking access to affordable medicines in areas its forces have occupied.
Viktor Liashko told the Associated Press that Russian authorities have repeatedly blocked efforts to provide state-subsidised drugs to people in occupied cities, towns and villages since the war began.
"Throughout the entire six months of war, Russia has not [allowed] proper humanitarian corridors so we could provide our own medicines to the patients that need them," Mr Liashko said, speaking at the health ministry in Kyiv.
"We believe that these actions are being taken with intent by Russia, and we consider them to be crimes against humanity and war crimes that will be documented and will be recognised," the minister claimed.
The Ukrainian government has a programme that provides medication to people with cancer and chronic health conditions.
The destruction of hospitals and infrastructure along with the displacement of an estimated seven million people inside the country also have interfered with other forms of treatment, according to United Nations and Ukrainian officials.
The war in Ukraine has caused severe disruptions to the country's state-run health service, which was undergoing major reforms, largely in response to the coronavirus pandemic, when Russian President Vladimir Putin ordered his troops to invade on 24 February.
The World Health Organisation said it recorded 445 attacks on hospitals and other health care facilities as of 11 August that directly resulted in 86 deaths and 105 injuries.
But Mr Liashko said the secondary effects were far more severe: "When roads and bridges have been damaged in areas now controlled by the Ukrainian forces … it is difficult to get someone who had a heart attack or a stroke to the hospital.
"Sometimes, we can’t make it in time, the ambulance can't get there in time. That’s why war causes many more casualties [than those killed in the fighting]. It’s a number that cannot be calculated."
