KYIV, Ukraine -- There will likely be further strikes into Russian territory, Ukraine's military intelligence head, Kyrylo Budanov, told ABC News in an interview from Kyiv, without specifically saying whether Ukraine would be behind them.Ukraine has not claimed responsibility for the Dec. 26 attack on Russia's Engels Air Force Base, which is located more than 800 miles from the Ukrainian border, but Budanov admitted he was "glad to see it.""There are hundreds of dead bodies just rotting away in the open field, in places they are piled on top of other bodies like makeshift walls, when Russian troops attack on that field they use those bodies for cover, like a shield," he continued."I want to express gratitude for all the help we had, and ask to continue to support Ukraine," said Budanov, telling U.S citizens, "I promise it will not take too long now, and every taxpayer in the U.S. will be able to see where every cent went.Budanov also said they are expecting U.S. Bradley Armored Fighting vehicles to be sent to Ukraine soon: "We are waiting for them."
