Last week, Ukrainian drone hunters picking up the debris from Russia’s nightly assault on their cities found a weapon that stood out from the rest.

It had an advanced camera, a computing platform powered by artificial intelligence and a radio link, allowing an operator to pilot it remotely from Russia. It also contained new, Iranian-made, anti-jamming technology, according to a Ukrainian drone expert.

Most Russian attack drones are black, said Serhii Beskrestnov, an electronics expert more widely known as Flash. The new one, he told The Associated Press, was white.

Inside, there were no markings or labels consistent with Russian-made drones. Instead, the stickers followed a “standard Iran labeling system,” Beskrestnov said.

Experts who spoke said the labels are not conclusive proof but the English-language words are consistent with how Iran marks its drones. It is quite possible, they said, that it was sold by Iran to Russia to test in combat. Moscow has pummeled Ukraine almost nightly with Iranian-designed drones.
