The UN's top humanitarian official has reiterated strong condemnation of deadly missile attacks on multiple Ukrainian cities on Monday, while a senior doctor from the capital's main children's hospital described to the Security Council the 'real hell' endured by patients and medical staff alike after it came under fire.

Two of the country's main specialist hospitals for children and women were heavily damaged along with key energy infrastructure, reportedly killing dozens of civilians, including children, and injuring over 110.
