Strikes were conducted against Ukrainian drone-making sites and energy infrastructure, the Defense Ministry in Moscow has said

The Russian military has conducted one large-scale and six group strikes against drone production facilities, energy infrastructure, and other military-related targets inside Ukraine over the past week, the Defense Ministry in Moscow has said.

The bombardment was in response to "Ukraine's terrorist attacks on civilian targets in Russia," the ministry said in a statement on Friday.

High-precision munitions, including Kinzhal hypersonic missiles, were utilized during the strikes, it added.

The targets of the Russian attacks included production facilities for Ukrainian long-range drones and the sites from where they are being launched, the statement read.

Other enterprises of the country's defense industrial complex and the energy infrastructure that powers them were hit as well, it said.

The attacks were also aimed at transportation and port infrastructure used by Kiev's forces, arms and fuel depots, and temporary deployment sites of Ukrainian military units and foreign mercenaries, according to the ministry.

On December 28-29, Kiev launched 91 long-range UAVs at the residence of Russian President Vladimir Putin in Novgorod Region. All of the drones were shot down by air defenses.

Moscow has condemned the attack as an act of "state terrorism" and promised a response. The Kremlin also said that the Ukrainian drone raid was not only aimed at Putin, but also "against [US] President [Donald] Trump's efforts to facilitate a peaceful resolution of the Ukraine conflict."

Shortly before midnight on Wednesday, Ukrainian UAVs hit a cafe and hotel in the village of Khorly in Russia's Kherson Region where some hundred people were gathered for New Year's Eve celebrations. At least 27 civilians, including two minors, were killed and 31 others injured in the strike and the blaze that it caused.

Moscow Mayor Sergey Sobyanin said on Friday that 26 Ukrainian long-range drones had been destroyed on approach to the capital overnight.
