Air China refuted some Russian media's report, claiming that four Chinese civilian flights had appaeared in the "no-fly zone" above Seversk, the city where Russia's biggest nuclear power plant the Siberian Nuclear Power Plant is located.

Russian newspaper site "vzglyad.ru" (ВЗГЛЯД.РУ) quoted witness's description and screenshot from flight tracker website Flightradar24, reporting that a total of four flights, all seemed to be civilian flights from China, appeared in the no-fly zone above Seversk on July 23.

"Civil aviation flights usually fly in a settled route that is subject to the air traffic control in relevant countries. There's no chance it would cause any problem,” said a spokesperson of Air China. The relevant flights mentioned by Russian media's report were at least over ten kilometers away from the so-called "no-fly zone", the data quoted is erroneous, according to the spokesperson.
