Russian forces appear to have become more aggressive in their targeting of infrastructure inside Kyiv which has seen an increase of missiles and artillery strikes, a senior U.S. official said on Wednesday.
"We've observed, certainly as you have all observed, an increase in missiles and artillery that (is) targeting the city and this (increasing) aggressiveness in terms of just the iron that they're lobbing into the city," the official said.
The official said that 450 missiles had been launched against Ukrainian targets over the past seven days by Russian forces.
