This was reported by Ukrinform with reference to NHK.

A team led by Watanabe Hidenori, a graduate professor at the University of Tokyo, updates digital maps online daily. The group uses satellite imagery released by American and European companies.

According to Watanabe, satellites using infrared radiation showed that large fires broke out one after another in several cities of the Luhansk region last month, indicating a brutal attack by Russia.

He also said that fires broke out in most of the small settlements near Kharkov.

Watanabe said in an online interview with NHK that Russia is likely to launch random attacks on non-military targets as part of its destruction strategy.

He believes that as many people as possible should understand with the help of digital maps that not only big cities, but also other regions that are away from the attention of the media have become battlegrounds.

As Ukrinform reported, on February 24, Russian President Vladimir Putin announced a full-scale invasion of Ukraine. Russian troops are destroying infrastructure, using artillery, multiple rocket launchers and ballistic missiles to heavily bombard residential areas of Ukrainian cities and towns.

The United States, the European Union and other countries have imposed sanctions against the aggressive country, whose international isolation is increasing day by day.
