“From our side, he was given the necessary medical assistance despite the grave crimes he committed,” she added.

The organisation said the pair went missing while driving to help a woman and two children evacuate.
The Presidium Network said it was concerned Russian forces may think the men are British spies.
The Foreign Office has said it is urgently seeking clarity about the situation.
A Foreign, Commonwealth and Development Office spokesperson said: “We are urgently seeking clarification from the Russian government on media reports that a British aid worker has died in Ukraine.”

“Absolutely devastated,” Linda Urey wrote.
In a second post, she wrote: “I’m truly angry I told you he was a very sick man, I told he he was diabetic, I begged on sky news to give me my son back why did you let him die I want answers why didn’t you release him...”
