Russian-made anti-drone electromagnetic jamming weapons have been smuggled into Russia-occupied Donbas.

"Russians have brought anti-drone electromagnetic weapons to Donbas. This is not science fiction – over the past years, the war in the east of Ukraine has become more technology-oriented and is not limited to 'iron gifts' from terrorists," NGO Povernys Zhyvym (Back&Alive) said on Facebook on October 21.

According to Back&Alive, anti-drone guns, like the REX 1 prototype developed and presented by Russia's Kalashnikov Concern in 2017, jam drone communications signals, make them land or pull them up. "Unfortunately, four Ukrainian drones have been lost on the front line this month," it said.

As UNIAN reported earlier, Russia-led forces attacked Ukrainian positions in Donbas, eastern Ukraine, 12 times on Sunday, October 20.

The hostilities in Donbas started in April 2014.
