Overview

• The UN Security Council will hold an emergency session at 10 a.m. New York time on September 22 at Estonia’s request, the first such appeal in Estonia’s 34 years at the UN.
• Estonia says three Russian MiG-31s entered its airspace near Vaindloo for about 12 minutes on September 19 and published a flight map, while Russia denies any violation and asserts the jets flew over neutral waters.
• Polish police reported new debris resembling drones in two Mazovian forests and opened investigations with military gendarmerie and prosecutors after earlier cross-border incursions this month.
• NATO and the EU condemned the actions as reckless and dangerous, Czech President Petr Pavel urged readiness to destroy airspace violators, and Poland’s defense minister called for a firm allied response.
• The Institute for the Study of War assesses Russia is testing NATO’s defenses and political resolve, as Ukraine’s General Staff logged 156 combat engagements on September 21 with the Pokrovsk sector remaining the most active.
