It is a dark day in Europe's history, said Foreign Minister Jeppe Kofod about Russia's invasion of Ukraine.
Russia is attacking Ukraine from several sides, just as the United States has warned.
Putin and Russia have had every chance of choosing a peaceful, diplomatic path - but they have chosen otherwise.
Denmark will now coordinate a hard and clear response with the European allies as well as the USA, Canada, Great Britain etc.
Danes who are still in Ukraine are encouraged to contact the Ministry of Foreign Affairs' Citizen Service.
