Secretary of State Marco Rubio and EU foreign policy chief Kaja Kallas engaged in a heated exchange during a G7 foreign ministers meeting on Friday, according to three sources who attended. Kallas, Estonia's former prime minister and known Russia hawk, criticized the U.S. for not increasing pressure on Moscow despite Rubio's previous warnings about American patience running out.

The confrontation occurred during discussions about Ukraine and highlighted growing tensions between the U.S. and European allies over war strategy. Kallas reminded Rubio that he had previously threatened stronger action against Russia if the Kremlin hampered peace efforts, asking when American patience would finally be exhausted after a year of Russian intransigence.
