Russian opposition politician Boris Nemtsov was shot to death in central Moscow late Friday, RIA Novosti reports.
According to Moscow police, Nemtsov was walking near Red Square with a female companion when assassins opened fire on him.
“A car approached, from which several shots were fired. Four shots hit Nemtsov in the back,” Ministry of Internal Affairs spokesperson Elena Alekseeva said.
Six shell casings were found at the scene of the murder. However, investigators think at least seven or eight shots were fired.
The court medical examiner later determined Nemtsov was killed by a bullet to the heart.
Moscow police are engaged in an active search for the shooter or shooters, who have not been identified. Several roadside police checkpoints have been set up in central Moscow.
