Russia is launching fewer missiles per attack and is increasing the intervals between attacks, a representative of the Ukrainian Defense Ministry claimed in a statement on Thursday.
The Russian military had used "everything that can move," and now has fallen back on Iranian "Shahed" drones and missiles originally meant for air defense like the S-300 missile systems, Defense Ministry Spokesman Andriy Yusov said.
"We can see that despite the massive missile attack, the infrastructure of Ukraine has withstood and will certainly endure. The enemy's missile potential is decreasing. They cannot maintain such a high intensity both in terms of regularity and in terms of quantity," he added.
Missile attacks targeting infrastructure
The comments were published on the same day a massive attack of 120 missiles further damaged Ukraine's energy grid as well as numerous civilian buildings.
However, claims that Russia is running low on munitions have been made throughout the over 10-month long war. Already in May, a representative of Ukraine's Intelligence Directorate claimed that Russia had severely depleted its missile stocks.
Reports have persisted throughout the war that Russia's defense industry has been unable to produce many of its more advanced munitions because of the rising prices of raw materials and limitations on foreign electronics caused by Western sanctions.
