The Russian armed forces have neutralized 400 Nazis and destroyed 11 Ukrainian military sites and eight ammunition depots using the high-precision P-800 Oniks cruise missiles, in addition to downing six Ukrainian choppers and MiG-29s, the Russian ministry of defense said Monday.

"Our missiles destroyed 11 military sites, four Nazi camps, eight ammunition depots, and two radar stations in Donbass," ministry spokesperson Igor Konashenkov said.

"The Russian forces managed to down 6 Mi-8 and Mi-24 helicopters in the town of Artsyz in Odessa, southern Ukraine, and 318 gatherings of Ukrainian forces. 400 Nazis were neutralized, and 48 military vehicles were damaged," Konachenkov said.

He also revealed that the Russian armed forces downed a MiG-29 and three UAVs in the airspace of Severodonetsk.

The Russian air defenses, according to Maj. Gen Konashenkov, intercepted a Ukrainian Tochka-U missile near the village of Ivankova, Kharkov, in addition to two BM-30 Smerch rockets in Izyum in Donbass.

The defeats the Ukrainian forces are suffering come despite the West supplying Kiev with arms and trying to bolster its capabilities against the Russian army.

Before the war in Ukraine, the United States had already given Kiev some $1 billion in economic aid, not to mention the additional $500 million cleared last week and the military aid the United States gave to Kiev since Biden took office.

The latest military aid package, worth some $800 million, made for a total of $2.4 billion in military aid the past month alone, and a total of $3.2 billion since Biden took office, according to figures provided by the White House.

Since the start of the war, the United States has deployed more than 100,000 of its troops to NATO member states, and the European Union also chipped in, sending $500 million worth of arms and equipment to Kiev.

The US is still sending arms to Ukraine despite the Russian ambassador to the US, Anatoly Antonov, warning that the influx of Western arms to the conflict zone in Ukraine was adding fuel to the fire.

Earlier in the day, a senior US Defense Department official revealed that Washington has transferred over 85 out of the 90 M777 howitzers that had been pledged for Ukraine during the ongoing war amid calls from Russia to halt arms shipments to Kiev as it would only make the situation worse.

The United States had committed a total of 90 M777s or 155mm howitzers to Kiev as part of the last two presidential drawdown authorities in a bid to further expand the Ukrainian military capabilities.

The US, the senior official added, will use the remaining $100 million in presidential drawdown funds.

"We still have a lot of the $100 million left and I'm sure we will use it. It's just a matter of how we work it out with Ukrainians," the official said.
