US Secretary of State Antony J. Blinken spoke with Ukrainian Foreign Minister Dmytro Kuleba to reaffirm the United States’ steadfast support for Ukraine’s sovereignty, independence, and territorial integrity, State Department Spokesman Ned Price said in a statement.

“Secretary Blinken expressed to Foreign Minister Kuleba that the United States rejects Russian Defense Minister Shoygu’s transparently false allegations that Ukraine is preparing to use a dirty bomb on its own territory and that the world would see through any attempt by Russia to use this allegation as a pretext for escalation,” Price said.
