"Please accept my sincere condolences and words of support in connection with the grave, irreparable loss that has befallen you," Putin said in a telegram.

The Russian president dubbed the crime as "vile, cruel," while describing Darya Dugina as "a bright, talented person with a real Russian heart."

"A journalist, scientist, philosopher, war correspondent, she honestly served people, the Fatherland, proved by deed what it means to be a patriot of Russia.

"The memory of Darya Dugina will forever be preserved by relatives and friends, her like-minded people and associates," Putin said, wishing her parents strength and courage.

Later Putin signed a decree, honoring Dugina with the Order of Courage, "for the courage and dedication she showed while performing her professional duty."

Dugina, 29, was the daughter of Russian sociologist and philosopher Aleksandr Dugin, who heads the International Eurasian Movement, a political movement which opposes American values like liberalism and capitalism.

Dugin was included in the list of "100 Global Thinkers of the Modern World" by Foreign Policy magazine in 2014. He is also on the US and EU sanctions lists because of his open support to Putin's policy.
