Irkutsk governor Igor Kobzev said the plane came down on a two-storey building in the city.
The local branch of Russia’s emergencies ministry said the Su-30 fighter jet crashed during a training flight and fell on a two-storied wooden building, sparking a fire.
The crash came less than a week after another Russian warplane crashed near an apartment building in the Sea of Azov port of Yeysk and exploded in a giant fireball, killing 15 and injuring another 19.
