“Both pilots were killed. None of the local residents were hurt… The Su aircraft was carrying out a test flight,” regional governor Igor Kobzev said on social media.
“According to preliminary data, a Su category plane hit a two-storey building in Irkutsk on Przhevalskogo street…”
Kobzev also posted a video of the building with smoke billowing against a dark sky and firefighters working at the scene.
Sunday’s crash is coming days after a military jet crashed into a block of flats in the Russian town of Yeysk.
