More than 30 are already in the Donbas region.US sending ‘urgent’ shipment of anti-tank missiles for fight in DonbasUkrainian forces are preparing for a major fight in the east as Russia prepares as many as 40 BTGs to join 30 more battalions already in Donbas.“They’re not waiting,” the official said. “They are already adapting to increased Russian activity in the Donbas region and doing the best they can.”On Tuesday, the Biden administration authorized a $100 million drawdown package to “meet an urgent Ukrainian need for additional Javelin anti-armor systems,” Pentagon press secretary John Kirby said in a statement.The senior U.S. defense official said this move was specifically to help in Donbas.“One of the reasons why you saw us describe this $100 million drawdown package last night as an urgent need for Javelins was in fact because of the activity in the Donbas and the Ukrainians wanting to make sure that they’re ready for increased Russian activity there,” the official said.Ukrainians get drone training in USA small number of Ukrainians currently in the U.S. for “professional military education” were pulled aside for a couple days of training on Switchblade drones, which the U.S. is sending overseas as part of its military aid, according to the official.“Although it’s not a very difficult system to operate, we took advantage of having them in the country to give them some rudimentary training on that,” the official said. “And there may be some additional rudimentary training while they’re here.”The official said fewer than 12 Ukrainians were given this U.S.-based training.Pentagon blames Russia for nitric acid explosionThe official said the Pentagon is “monitoring” an apparent nitric acid explosion in the Luhansk region, which Russia blamed on Ukraine.“We’ve seen the Russians claim that this was a Ukrainian attack on this. We do not believe that is true,” the official said. “We do believe that the Russians are responsible, but exactly what they used when they did it, why they did it, what the damage is, we just don’t have that level of detail,” the official said.‘Premeditated’ Russian atrocities in Bucha“When you see individuals with their hands tied behind their backs and evidence of being shot in the head, that certainly appears to be premeditated,” the official said, again calling for Russian war crimes in Ukraine to be investigated.Long-range strikes shifting eastRussia has now launched more than 1,450 missiles against Ukraine, according to the official. The Pentagon is seeing more airstrikes targeting the east than Kyiv as Russia shifts its overall focus to the Donbas region.Copyright © 2022, ABC Audio. All rights reserved.
