Days after the United States and dozens of other countries
counseled their citizens to leave Ukraine immediately, Russia early Thursday
launched an invasion of the country.

This post will be updated as events warrant.

• Ukraine on Thursday closed its airspace to all commercial
  flights, with the Ukrainian State Air Traffic Services Enterprise indicating on
  its website it would not provide air traffic services for civilian use. Some
  airlines already
  had suspended service to and from Ukraine, a number that grew in recent
  days. 

• Ukraine International Airlines suspended for Feb. 25 all
  scheduled and charter service to and from Ukraine, “in connection with the
  closure of Ukrainian airspace for civilian airspace users.”

• The European Union Aviation Safety Agency recommended
  commercial aircraft avoid not only the airspace of Ukraine and border areas of
  Russia but also Belarus and Moldova.
