The US State Department said Washington is in contact with Ukraine over its ground incursion into the Kursk border region. US State Department spokesman Matthew Miller said at a press conference that the Ukrainian operation "does not violate US policy on launching strikes on Russian territory." Miller said that Ukraine did not give the United States an advance warning about the operation. He stated that, "it is not unusual for the Ukrainians not to inform us of their precise tactics before they carry them out." "Ultimately, the decisions about how Ukraine conducts its military operations are its own," Miller added. Russia announced on Wednesday that it had been subjected to a major Ukrainian attempt to breach the border, through drone strikes, which were repelled. Russian President Vladimir Putin, in statements, considered the Ukrainian incursion into the Kursk region a major provocation, saying, "the Kiev regime has committed another major provocation," adding that Ukrainian forces are carrying out "indis criminate shelling of civilian targets in the Kursk region."
