WATCH: Secretary Blinken gives remarks on tensions between the U.S. and Russia over Ukraine

U.S. Secretary of State Antony Blinken will give remarks Thursday on tensions between the U.S. and Russia over Ukraine.

The event is scheduled to begin at 9:45 a.m. ET. Watch in the player above.

Earlier in the day, Blinken warned that there would be a “swift, severe” response from the United States and its allies if Russia sends military forces into Ukraine.

Blinken’s comments in Berlin appeared to be another effort to clear up any confusion about the position of the U.S. and its NATO allies after U.S. President Joe Biden was heavily criticized for saying a “minor incursion” by Russia would elicit a lesser response.

“If any Russian military forces move across the Ukrainian border and commit new acts of aggression against Ukraine, that will be met with a swift, severe, united response from the United States and our allies and partners,” Blinken told reporters.

Top American and European diplomats are seeking to project a united front to Russia over concerns that it may be planning an invasion of Ukraine.

Russia has massed an estimated 100,000 troops near Ukraine, and Biden said Wednesday he thinks Moscow will invade. He warned Russian President Vladimir Putin that his country would pay a “dear price” in lives lost and a possible cutoff from the global banking system if it does.

Against that backdrop, Blinken held talks Thursday with diplomats from Germany, France and Britain — a so-called Quad meeting. A day earlier, he met Ukraine’s president in Kyiv to discuss the threat.

Russia has denied it is planning an invasion and, in turn, accused the West on Thursday of plotting “provocations” in Ukraine, citing the delivery of weapons to the country by British military transport planes in recent days.
