What weapon might Ukraine have used to strike Tver ammo depot in Russia

According to OSINT analyst George Barros, the entire site is engulfed in smoke, Defense Express media and consulting company reports. 

Speculation arose about whether a new Ukrainian Palianytsia drone-missile struck the warehouses, as the sound of a jet engine was heard in footage of the attack. Based on the published images, Defense Express suggests that either a large number of Palianytsia drones hit the warehouse or a more powerful domestic missile, possibly a modernized Neptune, was used.

“The images show that the scale of the fire doesn’t match the “drone debris” claim by the Russian administration or the damage from just one or a few drones,” Defense Express stated.

The media and consulting company notes that these conclusions are preliminary. The true extent of the damage will only be clear once the fire is fully extinguished.

“Only then can we confirm whether North Korean KN-23 ballistic missiles or Russian Iskander missiles were stored there. Currently, we can dismiss claims that tactical nuclear warheads were involved, as such an explosion would have caused a significant radiation leak detectable across Eastern Europe and Ukraine,” 

• In the early hours of September 18, a drone attack triggered a fire and explosions at an ammunition depot in Toropets, Tver region. Authorities have ordered a partial evacuation of the area.
• Defense Express military expert Ivan Kyrychevskyi said that the explosions on September 18 in Russia’s Tver region were unprecedented in world military history.
