The violation of NATO member Estonia's airspace by three Russian military jets on Friday was an "extremely dangerous provocation", the EU's foreign policy chief Kaja Kallas said.
"This marks the third such violation of EU airspace in days and further escalates tensions in the region," Kallas said in a post on X.
"We will continue to support our member states in strengthening their defences with European resources. Putin is testing the West's resolve. We must not show weakness."
