Ukrainian naval drones shoot down Russian jets in military first, Kyiv says

The Kremlin said Russia's offer of a brief cease-fire is a test of Ukraine's willingness to work toward peace

Ukraine said it downed two Russian jet fighters using sea drones equipped with modified U.S.-made missiles, in what military officials in Kyiv said is the first such attack in the history of warfare.

Magura-7 sea drones deployed by Ukraine's military-intelligence agency, known as HUR, fired the missiles at two Su-30 jets that were flying near the Russian Black Sea port of Novorossiysk, HUR said.

Russia's military hasn't commented on the attack, which The Wall Street Journal wasn't able to verify.

The shootdowns demonstrate the threat Ukraine poses to Russia, with a military-industrial complex that is innovating in order to hold its own against Moscow's much-larger military.

With Russia grinding slowly forward on the battlefield and Ukraine struggling with a deficit of arms and manpower, the smaller country has found ever more enterprising means of weakening its enemy.
