A typical sound of the suburbs echoes through the Saltivka district of northern Kharkiv — a low, humming buzz like a lawnmower. Yet nobody has their own garden in this vast Soviet housing project, and there’s barely a blade of grass in sight.

Instead, the high-pitched noise in Saltivka’s concrete jungle comes from Iranian-made Russian drones, whose cheap gasoline engines sound just like the average home lawnmower.

Russian forces have been pounding Kharkiv with them for the last month, aiming to knock out power supplies as the winter temperatures plummet to -13 Fahrenheit.

But as the drones aren’t known for their accuracy, many crash-land in Saltivka, whose high-rises on Kharkiv’s northern outskirts lie just 20 miles from the Russian border.

The latest one slammed into a five-story tower block on Tuesday afternoon, leaving the top two floors a blackened wreck and injuring six, including a 90-year old woman. By local standards, that made it a low casualty count — if by accident rather than design.

“I have lost count of how many times they’ve fired drones at us in the last month,” Kharkiv’s weary-looking fire brigade spokesman told The Post at the scene. “The Russians are attempting to hit critical infrastructure, but to be honest, there’s no real logic to their strikes at all — it can be kindergartens, schools, hospitals, whatever.

“It’s all just to try and destabilize us. But whenever it happens, our emergency services come together, we clean things and we replace windows. We are the best.”

Odd as it may seem, the spokesman takes a certain municipal pride in Kharkiv’s ability to take punishment. This may partly be due to the busloads of helpers who arrive at every bombing with a pop-up stall dispensing hot soup and tea.

But it may also reflect how Kharkiv — the regional capital of Ukraine’s northeast — is coping better than Kyiv, which has likewise been pounded by Russia during the recent cold snap.
