Officials are considering Maxim Borodin's death to be a suicide.
A Russian journalist who wrote about Russian mercenaries in Syria has died from injuries he sustained after falling from a balcony.
The Associated Press reported that it was unclear how Borodin fell, but RFERL reported that officials are considering his death to be a suicide.
Borodin wrote for a news website called Novy Den where he covered crime and corruption, RFERL reported. He recently helped break the story about the deaths of Russian Wagner Group mercenaries from Asbest who were killed in Syria during a fight with the US military in February.
Borodin's editor at Novy Den, Polina Rumyantseva, said on Sunday that she doesn't believe he committed suicide, RFERL reported.
Reporters Without Borders tweeted on Sunday that the circumstances of Borodin's death were "suspicious," and that they want "a thorough, impartial investigation."
The Wagner Group has about 2,500 mercenaries in Syria, according to the BBC.
