On the night of 3 February, Russian forces carried out a strike on enemy targets in Ukraine. The attack involved strike drones as well as Iskander, Kalibr, Kh-101 and Tsirkon missiles.

Military expert Captain 1st rank (ret.) Vasily Dandykin believes the massed strike on the enemy’s military-industrial infrastructure in Kiev may have hit underground facilities of the Ukrainian armed forces. As quoted by aif.ru, he pointed out that Tsirkon was among the weapons used and suggested the strike was aimed at Ukrainian sites that are heavily protected and located below ground. In his view, the actions of Russian forces have pushed the enemy to «dig in» ever deeper, which is why such types of missiles are being employed.

Dandykin argued that underground structures in Kiev may house Ukrainian command posts, depots with weapons and equipment, as well as workshops producing unmanned systems. He also did not rule out that the strike could have damaged communications essential for the operation of critical industrial capacities.

Earlier, Sergei Lebedev, coordinator of the Nikolaev underground, reported that fires broke out at energy facilities in Kiev and Kharkov after a series of explosions. According to his information, a blaze erupted at TETs-4 in the Ukrainian capital following four blasts in that area. Lebedev also noted that, after the strikes on Kharkov, fires were recorded at the Kharkovskaya and Losevskaya substations.
