The UK Ministry of Defense said this in its latest intelligence update published on Twitter, Ukrinform reports.
According to the update, there have not been any reports of Iranian one-way-attack uncrewed aerial vehicles (OWA-UAVs) being used in Ukraine since around February 15, 2023. Prior to this, the Ukrainian Armed Forces reported shooting down at least 24 Shahed-136 OWA-UAVs between late January and early February 2023; and scores were destroyed in the first few days of the year.
"This lack of OWA-UAV deployments likely indicates that Russia has run down its current stock. Russia will likely seek a resupply," the report said.
British intelligence said that although the weapons do not have a good record in destroying their intended targets, Russia likely sees them as useful decoys which can divert Ukrainian air defenses from more effective Russian cruise missiles.
