The Ukrainian military says its new weapon system, which launches antiaircraft missiles from a remote-controlled speedboat, has brought down two Russian jet fighters.

NBC News has analyzed satellite imagery to dig into the claims being made by Kyiv and Moscow as part of a wider propaganda war being waged in parallel to the actual fighting.

Trump declined to say what those consequences would be, and went on to add that he had not had discussions about whether to investigate Musk.

Russia launched a massive attack on Ukraine's Kharkiv, killing four and injuring dozens. President Zelenskyy condemned the violence and appealed for urgent air defense assistance.

Ukraine said its “Operation Spiderweb” attacked Russian warplanes worth hundreds of millions of dollars, utilizing drones that each cost under $1,000 and were launched from wooden containers carried on trucks.

An analysis by multiple experts of new video and satellite images suggests that at least 11 Russian bomber aircraft and one large transport plane were badly damaged or destroyed in Ukraine's drone attack on Sunday.

Ukraine recently used inexpensive drones to inflict serious damage to Russia's strategic bomber fleet in an audacious attack.

Drones are “ubiquitous, because they are quite useful, and they're demonstrating that every day in Ukraine,” one analyst told NBC News.

Ukraine says that a large Russian drone-and-missile attack has targeted the eastern city of Kharkiv, killing at least three people and injuring 21.

Both sides are now using large numbers of attack drones controlled via fiber optic cables which are immune to radio jamming making them effectiveley unstoppable.

The Pentagon notified Congress last week that it will be diverting critical anti-drone technology that had been allocated for Ukraine to US Air Force units in the Middle East, according to correspondence obtained by CNN and people familiar with the matter.

On a “hot night,” when Russia tries to overwhelm Kyiv’s air defenses, Ukraine relies not only on Patriot missiles, but on civilians wielding searchlights and vintage guns.
