Ukraine continues to present a "significant challenge" to Russian air and missile operations, leaving Russian aircraft vulnerable to short and medium range air defense systems, the United Kingdom's Ministry of Defense said Sunday, APA reports citing CNN.
"Russia’s inability to find and destroy air defence systems has seriously hampered their efforts to gain broad control of the air, which in turn has significantly affected their ability to support the advance of their ground forces on a number of fronts," the ministry wrote in a defense intelligence update posted on Twitter.
The ministry also reported a concentration of Russian air activity towards south eastern Ukraine, "likely a result of Russia focusing its military operations in this area," it said.
Russian naval forces continued to prevent Ukrainian resupply by sea with a "distant blockade" of the Ukrainian coast in the Black Sea and Sea of Azov, the ministry said, though an amphibious landing from Russian forces was likely to be "increasingly high risk" due to Ukrainian preparations.
Reported mines within the Black Sea also "pose a serious risk" to maritime activity, the ministry said, adding that although the origin of such mines remains unclear and disputed, "their presence is almost certainly due to Russian naval activity."
