Ukrainian authorities have said that a fourth Russian general has been killed by the country’s forces.

47-year-old Major-General Oleg Mityaev is said to have died in the storming of Mariupol, along with seven members of an elite SWAT team.

A picture of the corpse of the decorated military officer, a father-of-two, was released by Ukrainian Interior Ministry adviser Anton Gerashchenko.
