Oksana Leontieva

was a

doctor in the children's bone marrow transplant ward

at the Okhmatdyt Children's Cancer Hospital in

Kiev.

Yesterday she was on her way to work, after leaving her child in kindergarten, when

she was killed by Russian raids on the center of the capital

.

The news - reports the British newspaper “The Guardian” - was the same hospital that on Facebook described Leontieva as "

a dedicated and responsible person and doctor. A true professional and a support for his patients and colleagues

".

Anton Gerashchenko, Volodymyr Zelensky's senior presidential adviser, stressed that now

her five-year-old son has been orphaned

because, as he also recalled on Twitter, Oksana had lost her husband six months ago. 

Doctor Leontieva is one of the

many names in the tragic outcome of what has gone into the news as "Putin's revenge"

for the attack on the bridge in Crimea.

A doctor from the Kiev children's hospital team, anesthetist Ekaterina TkachenkoI, writes on her Facebook profile: "

A Russian terrorist killed a wonderful person, one of the best doctors and a loving mother with a missile. Every day, Oksana. he saved children with cancer, gave happiness to parents and life to children ... And today his life has been broken by terrorists who destroy our country and kill civilians every day

".

There are also many

messages and appeals to support the doctor's son

, little Grish, who has only his maternal grandfather left.
