The Russian Defense Ministry said two Ukrainian drones were shot down by Russian air defense systems in the Kursk and Bryansk regions.

"On September 25, 2023, at about 10 a.m. [local time, 7:00 GMT], another attempt by the Kiev regime to carry out a terrorist attack using an aircraft-type UAV on objects on the territory of Russia was prevented. On-duty air defense intercepted two Ukrainian unmanned aerial vehicles over the territories of the Kursk and Bryansk regions," the Ministry said.

Concurrently, the Defense Ministry also announced that the Russian air defense systems successfully intercepted and brought down a Ukrainian drone in the Belgorod Region.

"On September 25, at about 09:00 Moscow time [06:00 GMT], an attempt by the Kiev regime to carry out a terrorist attack by an aircraft-type UAV on objects on the territory of Russia was stopped. On-duty air defense systems destroyed a Ukrainian unmanned aerial vehicle over the Belgorod Region," it said in a statement.

In the same context, Russian air defense systems took down four Ukrainian drones in the Black Sea area and over Crimea, as per the Ministry.

"On the night of September 25, 2023, an attempt by the Kiev regime to carry out terrorist attacks using fixed-wing drones against targets on the territory of the Russian Federation was prevented. Air defense systems destroyed four unmanned aerial vehicles over the northwestern part of the Black Sea and over the territory of the Republic of Crimea," the ministry said.

Running out of choices: Ukraine becomes overreliant on drone attacks

It is worth noting that the Ukrainian army has become overreliant on the use of long-range missiles and attack drones, as its counteroffensive is proving to be a failed mission.

Last Thursday, the Russian Defense Ministry said the Ukrainian armed forces (AFU) attacked Russia's Sergei Kotov patrol vessel of the Black Sea Fleet using five drone boats overnight, but all drone boats were destroyed.

At the time, the Russian Defense Ministry said Russian air defense systems had also shot down 11 Ukrainian aircraft-type unmanned aerial vehicles over Crimea overnight.

In further detail, Russia said it had destroyed several Ukrainian drones in its border regions of Bryansk and Belgorod during the night from Wednesday to Thursday.

The Ministry said six drones had been shot down in four separate locations over the Bryansk region, which is roughly equidistant between Kiev and Moscow.

In the same context, another drone was destroyed further south over the Belgorod region on Wednesday evening, the Defense Ministry added, saying the attempted attack had been thwarted.

Ukraine launched last Wednesday a total of 10 cruise missiles toward the Sevastopol shipyard, resulting in damage to two ships that were undergoing repairs, as per the Russian Defense Ministry. The attack also reportedly involved three unmanned boats.
