Secretary of State Marco Rubio gave assurances that the U.S. will not make concessions to Russia’s Vladimir Putin that go against the red lines of Ukraine and Europe, the European Union‘s High Representative Kaja Kallas said.

Rubio is in Brussels for a meeting of NATO foreign ministers. Kallas was asked if Rubio had given such assurances in his discussions with European NATO allies so far.

“It was stressed that nothing about Ukraine without Ukraine, and of course Ukraine and Europe need to be agreeing to whatever is discussed because this is all happening in Europe,” Kallas told reporters on Friday morning.

“So, yes, he was giving us assurances about this.”

This is a developing story and more information will be added shortly.
