Overview

• Unidentified drones forced hours-long closures at the main airports in Copenhagen and Oslo, disrupting or canceling dozens of flights as police and security services investigate without naming an operator.
• Denmark’s prime minister called the episode the most serious attack on critical infrastructure to date, while the Kremlin denied any role and NATO’s secretary-general said it is too early to attribute responsibility.
• At Estonia’s request, NATO ambassadors met in Brussels and urged Russia to end escalating airspace violations on the alliance’s eastern flank, vowing to use military and non-military tools consistent with international law.
• The dispute over Estonia’s claim that three Russian MiG-31s intruded for about 12 minutes reached the U.N. Security Council, where U.S. and U.K. officials warned unauthorized aircraft would be confronted and Russian diplomats rejected the allegations.
• EU foreign policy chief Kaja Kallas labeled the pattern a provocation and backed fresh sanctions proposals, and Germany signaled a sharp rise in defense spending citing the threat to NATO’s eastern members.
