Baulina previously worked for Russian opposition figure Alexei Navalny's anti-corruption foundation, and had left Russia.

Last year the foundation was made illegal and branded extremist by the authorities, forcing many of its staff to flee abroad.

One other person was killed and two injured in the shelling, the Insider said.

Baulina had previously sent several reports from Kyiv and the western Ukrainian city of Lviv, The Insider said.

The publication expressed its "deepest condolences" to the reporter's family and friends.

Investigative journalist Alexey Kovalyov paid tribute to Baulina.

Baulina is one of five journalists known to have been killed in a month of war.
