 The explosion that occurred in Russia's Belgorod city may have been caused by a cruise missile that was fired from a Russian plane at Kharkiv but fell on the city, Ukrainian telegram channels reported. The power of the explosion and the large pit created after the incident give the reason to come to this conclusion. However, local telegram channels reported that the explosion took place in the air and that the air defense system was activated. It should be noted that Belgorod region is located on the border with Ukraine's Kharkiv region.
