Recent Ukrainian drone alerts near Moscow have triggered repeated temporary suspensions of operations at the city's major airports, including Sheremetyevo, Vnukovo, Domodedovo, and Zhukovsky. In early September 2026, President Zelenskyy publicly warned airlines and insurers that Russian airspace had become unsafe for civil aviation due to intensified drone activity tied to the ongoing conflict, prompting Ukraine to notify the ICAO. Russian authorities responded by activating the "Carpet" emergency protocol on multiple nights, citing unidentified aerial threats and air defense engagements that forced flight delays, cancellations, and diversions. Several international carriers adjusted or canceled routes in response. These developments, occurring within the past week, directly shape trader focus on the timing, frequency, and attributed causes of further disruptions.
