The prime ministers of the Czech Republic, Poland and Slovenia were travelling to Kyiv by train on Tuesday to show support for the country on behalf of the EU, the first foreign leaders to visit the Ukrainian capital since Russia invaded last month. Kyiv has been under Russian attacks: two powerful explosions rocked the capital before dawn on Tuesday. Polish Prime Minister Mateusz Morawiecki said on Facebook the trip took place on the 20th day of Russian President Vladimir Putin’s Putin’s “criminal aggression against Ukraine”.
