Ukrainian "kamikaze" drones attacked a metallurgical plant and other facilities used for military purposes in Russia's Belgorod, Voronezh, and Lipetsk oblasts overnight on June 17, Ukraine's military intelligence (HUR) source told the Kyiv Independent.
The confirmation came after Russian governors reported drone attacks on three regions, claiming there were no damage or casualties.
One of the targets was the Novolipetsk metallurgical plant and a local tractor plant in Lipetsk Oblast, according to the source.
"Both enterprises are used by the aggressor for military purposes. In the area of these facilities, local residents heard the sounds of explosions and air defense systems," the source said.
Information about the consequences of the attack is being clarified, the source added.
Igor Artamonov, Lipetsk Oblast governor, claimed that debris fell after two drones were intercepted over Lipetsk industrial area.
The Kyiv Independent could not verify these claims.
At least 70 drones attacked the Morozovsk airfield, located in Russia's Rostov Oblast, overnight on June 14, Ukraine's military intelligence head Kyrylo Budanov confirmed.
The HUR chief said that he was "waiting for information" about the extent of the damage caused at the airfield, which satellite imagery has confirmed hosts Su-34 fighter jets.
