Eastern Europe: Countries bordering Ukraine, Belarus, and Russia increase border security as of Feb. 24

Event

Several countries sharing borders with Ukraine, Belarus, and Russia have announced heightened security measures following Russia's Feb. 24 military offensive into Ukraine. Multiple NATO members in the region have invoked Article 4 of the NATO treaty and could increase the readiness of their militaries as a result, though this is not an indication that they expect to become engaged in the conflict.

Moldova and Lithuania have enacted states of emergency. Moldova has also closed its airspace and the European Union Aviation Safety Agency (EASA) has warned against flying over or near Ukraine. Slovakia has suspended international rail services with Ukraine. Moldova, Slovakia, Hungary, and Poland are all keeping their respective borders with Ukraine open and are making preparations to receive refugees; these countries are also likely to maintain a heightened troop presence near their borders with Ukraine over at least the short term. Enhanced security measures and a sharp increase in individuals attempting to leave Ukraine will likely result in border crossing delays.

Advice

Avoid nonessential travel to affected border regions; defer travel to Ukraine. Confirm border crossing status before beginning any journeys; if leaving Ukraine, consider departing via a border crossing recommended by your diplomatic mission and allow extra time for processing. Heed all instructions from border staff. If in Ukraine and not en route to a border crossing to leave the country, shelter in place until the situation becomes clear. Maintain contact with your diplomatic representation.
